Safety instructions

All electrical work shall be carried out

exclusively by licensed electricians.

When installing or repairing electrical

equipment, always be sure that it is

completely isolated from the supply. Do

not work on live parts.

Install the controller in a dry room and

at a location where it is not exposed to

Wall-mount enclosure installation

Tools and installation

The following tools are required to in-

stall the controller:

• drill

• 6 mm drill bit

• Screwdriver

Open up the enclosure. You can use

the bottom part as a template to locate

the mounting holes. Drill 6 mm holes at

the marked locations. Fasten the bot-

tom part of the enclosure to the wall

using the anchors and screws provided.

Connect the sensor, supply and pump

wiring to the terminals as shown in the

diagram below.

Mount the controller on the connector

provided. You can now refasten the

bottom cover of the enclosure. Ensure

that the electrical wiring is connected

properly and use the strain relief provi-

sion when fastening the wires.

Sensor location

The collector sensors shall be mounted

in the supply connection (hot side) of

the collector.

Some solar system components can

become very hot (risk of burn injuries).

The return-line sensors can be mounted

in the lower part of the storage tank or the

return line from the solar heating system.

Thermowells are installed about halfway

up the storage tank to mount the upper

storage tank sensors.

Domestic water backup heating using a boiler

When the LOGON SOL plus controller

is used to control a boiler that provides

supplemental heat for the domestic

water, it must be interconnected with

the boiler controller (sensor-side termi-

nals 14 and 15, see connection dia-

gram). The following LOGON SOL plus

features make it capable of interacting

flexibly with the boiler controller. A

jumper located on the back of the con-

troller can be used to choose between

a changeover switch with resistors and

a zero-resistance changeover switch.

Place the jumper in position Y to use

LOGON SOL plus in conjunction with

LOGON controllers (SYSTRON,

UNON, VARION) to control domestic

water backup heating (see diagram).

The connected resistors are used to

simulate temperatures.

Off = 1320 ohms = 70°C

On = 8200 ohms = 25°C

Place the jumper in position X to use

LOGON SOL plus in conjunction with

non-LOGON controllers (THISION,

TRIGON, STRATON or third-party boil-

ers) to control domestic water backup

heating. This selects a changeover

switch with zero resistance.

The jumper is in position X when the

controller leaves the factory.

After installing the controller, choose

the correct system configuration

(number of collectors/storage tanks)

from the system circuit diagrams pro-

vided.

The manual shows the wiring for the

required sensors and relays for the

selected circuit schematic.

The respective "Sensor assignment"

tables identify which additional sensor

inputs can be connected.

The respective "Relay assignment"

tables identify which relays are avail-

able for additional functions.

The connections and settings for the

most important auxiliary functions are

summarized in the manual. If it be-

comes necessary to choose settings for

the system that deviate from the factory

settings, the changed values should be

noted in this manual. This will be useful

for later servicing of the installation.

In addition, the Info sequence shows

the total heat gain (ERT), the daily heat

gain (ERTd) and the speed of pumps

P1.. P3 (ED1..ED3).

It is preferable to use a volume flow

sensor for the total or daily heat gain

calculation. Parameter VSA = 1 or 2

(E3-4.3) confirms that a volume flow

sensor is being used. The heat gain

display is enabled when confirmation is

received that a volume flow sensor is

present.

If no volume flow sensor is present,

heat gain values can only be dis-

played if the minimum lower set

point for the heat transfer pump is

set to 100 percent. In this situation the

heat gains are calculated on the basis

of the default liquid flow rate.

ERT total heat gain in kWh; range 0 .. 199999 kWh

Total heat gain can be reset to zero by pressing and holding the [-] key for five seconds while a value is being dis-

played.

ERTd daily heat gain in kWh; range 0 .. 999 kWh

The day's heat gain can be reset to zero by pressing and holding the [-] key for five seconds while a value is being dis-

played.

ED1 speed of pump P1 in %, range 30 .. 100 %

ED2 speed of pump P2 in %, range 30 .. 100 %

ED3 speed of pump P3 in %, range 30 .. 100 %

The speeds (ED1 … ED3) are only displayed if the respective minimum set point (USW1.. USW3) is < 100 %.
