1. General

1.1. Tender text

multicontrol modular for lossless storage of the expansion volume and for pressureMCM

maintenance in closed heating, climate and cooling systems. Designed and manufactured acc.

to regulations of 12828 and 93-1.EN SWKI

The multicontrol device is a nicely shaped, self-contained unit with a pleasing design. It isMCM

designed for a modular combination with external expansion vessels (max. 0.5 bar). The

connections for suction pipe and overflow pipe are situated at the back of the device.

The control unit is built very compact with one resp. two low-noise pressure maintenance

pump(s) (model Solo 1x100%, model Duo 2x50%, model Maxi 2x100%) which is/are executed as

multistage centrifugal pump(s) with high quality floating-ring type shaft seal. Also the

multicontrol hydraulics includes one resp. two continuously regulating, mechanically set

overflow valve(s) (models Solo, Duo and Maxi 1x100% of the expansion flow, models Duo-twin

and Maxi-twin 2x100%). High-precision measuring of the plant pressure. Hydraulic connections

and necessary shutoff devices for on-site piping are factory provided on the left side of the

control unit (possibility for rebuilding to the right side of the control unit). Temperature

monitoring of the media streaming into the vessel.

Prepared connection point for mounting a makeup module for litre accurate measuring.

Combinable with water softening for standardized makeup water.

Prepared connection point for mounting a degassing module for automatic and economic low

pressure degassing, based on the principle of pressure drop. The connection and the necessary

shutoff device for the degassing pipe is situated at the back of the control unit.

All operations are controlled by the microprocessor electronics. The operator panel is situated

ergonomically and containes a illuminated 4-line text display. The handling is thought-out and a

lot of languages are supported. The measure- and control unit is executed in a closed electrical

cabinet. Four potential-free signalling contacts (fault, warning, makeup in operation, device

operation enabled).

For more signals two additional expansion modules can be installed easily in prepared mounting

positions. Remote monitoring can be done also via multicontrol module or multicontrol busSMS

module. External temperature monitoring via an optional temperature sensor at the connection

point is prepared too.

step 6 Switch on power supply and check if the red control lamp beside the key ”0”

glows. If not, deactivate the device by pressing the key ”0” and following

confirmation by pressing the key ”F1” (red control lamp beside the key ”0”

must glow!)

step 7 Fill and ventilate the pressure maintenance pump(s) and the piping.

- The Shut off devices at the intake side of the pump(s) must be opened com-

pletely and the regulating valve at the pumps outlet side must be closed

completely.

- Open the ventilating valve at the pump(s)

figure : ventilation valve at the pump4

- If a makeup module is installed, go to manual mode (user level 3), seeMCF

instruction manual , -_1, chapter 5.7, ”user level 3”.MCK MCM

- Switch on the output ”makeup valve Y1” (”output: on”) and fill the vessel until

a continuous water jet leaks from the ventilation valve at the pressure mainte-

nance pump. After this set the output ”makeup valve Y1” to automatic mode

(”output: auto”).

Detail A

- If a makeup module is not installed, you have to fill the vessel (e.g. viaMCF

the emptying at the connection of the overflow pipe - see figure 5, detail B) until

a continuous water jet leaks from the ventilation valve (detail A) at the pressure

maintenance pump.

- To ensure a complete ventilation of the pump start and stop the pump in manual

mode (”output: Test”, operate with ”F1”) several times.

- In the course of these pump starts you have to check the direction of the rotation

of the pump motor. The fan wheel must rotate according to the sticker on top of

the motor cover. You can see the fan wheel through the holes of the pump cover.

figure 5: Checking the direction of rotation of the pump motor

- If the fan wheel doesn‘t rotate in the right direction, you have to change 2 of the 3

phases to weaken the rotating field and the direction of the rotation.

- Close the ventilation valve of the pressure maintenance pump.

- At devices with 2 pressure maintenance pumps (system Duo and Maxi) repeat

the above steps for the second pump (pump 1 = left side, pump 2 = right side).

step 8 Configuration of the multicontrol device

- Press the key “F2” (operate) in main display

- select menu item “code input”

- Enter the code (see instruction manual multicontrol , -_1,MCK MCM

chapter 5.7 “user level 3”)

- User level 3 is unlocked

step 9 Enable the device by pressing the key “I” in main display and confirm it by

pressing the key ”F1” (Yes) (green control lamp beside the key „I” must glow!)

step 10 Adjust the pressure maintenance pump(s)

Due to the necessary working pressure the pump(s) must be adjusted on the

output side. This adjustment must be done because the delivery rate of the

pump(s) (acc. to their characteristic curve) rises at low pressures.

A hint for a necessary adjustment could be:

After pump stop the overflow valve doesn‘t close completely before approx.

0,5 bar under the upper working pressure.

The setting (1) of the regulating valve(s) must be notated

at the plant- resp. commissioning record.

5. Commissioning

NOTE!

The adjustment of the pressure maintenance pump(s) must be done before the setting of the

working pressure! After this neither the working pressure nor the adjustment must be

step 11 Set the working pressure

- Open the shut off devices from/to system return expansion pipe, makeup).(

If a degassing module is installed, the ball valve at its intake side must beMAE

closed.

Due to the size of the system the setting of the working pressure can take up a

lot of time because the pressure has to extend into the entire connected system

to be stable for the setting.

- Go to user level 3 (see step 9).

- Select “settings” “pressure maintenance” “working pressure”gg

- The display shows the current settings (complies with the last set working

pressure, e.g. default value ex factory)

: Independent to the displayed values the working pressure mustCAUTION

be set again in the course of commissioning!

- Press the key “F1” (change) to start the pump.

- Set the overflow valve to the upper working pressure (determined in step 1), the

current pressure is shown at the display.

overflow valve via

(a) ,black hand wheel

(b) hexagonal nut at the spring cap

(depends on the used type of the

overflow valve).

- Do not confirm the set upper wor-

king pressure until the desired

pressure is not stable for a few

minutes! (confirm with “F1” (apply)

- Enter the hysteresis (default value: 0,5 bar)

Difference between the set upper working pressure (set at the overflow valve)

and the start-up pressure of the pump (=lower working pressure).

- In devices with 2 overflow valves (system Twin), both valves must be set one by

one. One of these valves must be shut off, at the other one the upper working

pressure can be set. Then the set valve must be shut off and the other one can be

set - repeat the above steps (set both valves to the same pressure!)

figure 7: setting of the overflow valve

NOTE!

In Twin devices only one overflow valve must be in operation, the other one must be shut

off at its intake side. If both valves are in operation at the same time, the control behaviour

can be influenced negatively (e.g. too big hysteresis). Therefore this must be avoided!

step 12 If a makeup module is installed, the operating mode must be selected.MCF

The operating mode is depending on several criteria such as size of the system,

age of the system, possible known leakage and so on.

If there are known and regular leakages (e.g. a known makeup amount within a

known period) we recommend to use the operating mode ”time-controlled”.

For a description of the different operating modes see instruction manual

multicontrol , -_1, chapter 5.7 - “user level 3”.MCK MCM

step 13 If a degassing module is installed, the operating mode ”degassing module”MAE

must be selected. If the selection happened incorrectly, degassing can‘t work

correctly!

:Adjustment of the degassing module

- Shut off the regulating valve and the ball valve at the degassing module.

- Go to manual mode (user level 3) see instruction manual ,( multicontrol MCK

-_1 chapter 5.7 “user level 3”) and switch on the output ”degassing valve”MCM ,

(”output: on”)

- Wait until the motor valve opened completely (ca. 35 sec.; the scale resp., the

red axis at the electric actuator must not rotate anymore).

- Open the ball valve at the intake side.

- Open the regulating valve slowly until you hear a flow (ca. 1/4 turn). The plant

pressure decreases, the pressure maintenance pump starts.

- Look for the plant pressure shown at the display.

- The regulating valve is set correctly, if pump 1 is able to increase the plant

pressure and stops. If the pump can‘t increase the plant pressure resp. the

second pump (systems Duo, Maxi) starts, the regulating valve is set incorrectly

(opened too much).

- After this, the output ”degassing valve” must be set to ”Auto” again.

- (1)The setting of the regulating valve must be notated

at the plant- resp. commissioning record.

: _________setting regulating valve MAE (1)

step 14 The device is now ready for operation.

All shut off devices from/to system return must be secured against unintended

closing (e.g. by dismantling the handle,...)

Further settings (e.g. water treatment, operating modes etc.) must be done in

menu ”settings” (see instruction manual , -_1).MCK MCM
