Controller settings

User settings

a) Time switch (analog or digital)

b) Position selector

c) Display

d) Temperature setting

e) Function switch

f) User instruction

a) Time switch

If heating circuits are to be time

controlled build in one of below time

switches:

- 1-zone analog time switch

- 2-zone digital time switch

The control is not set for a built-in time

switch ex factory, but for constant normal

temperature in both heating circuits. So

P8.4 (time switch channel selection) is to

be changed - see paragraph on digital

settings.

Push slides towards the centre for

reduced temperature operation thus

required normal and reduced periods are

set on the analog time switch.

The digital time switch is set as

described in the user guide supplied with

the time switch.

b) Position selector

Position selector has positions 0-9.

Below table shows controller display c)

og each setting.

Position selector can also be used for

many other settings. Read paragraph

"Digital settings".

c) Display

Temperature indication as mentioned in

b). Read paragraph "Digital settings)

d) Temperature

Temperature setting operates in

accordance with P8.2 settings (see

section on digital settings). Weather

compensation or adaptive reference

room control are selected in P8.2.

Weather compensation

Flow temperature both in boiler circuit

and mixing circuit can be increased and

decreased (parallel-displaced) by turning

the knob. Turning towards +8 increases

the flow temperature.

Since parallel displacement depends on

heat curve slope, temperature changes

in the two heating circuits might differ.

BC-HM VI.74.D2.02 © Danfoss 11/96 7

ESMR/F reduces flow temperature when

set max. room temperature is exceeded.

Max. room temperature is factory-set at

22 °C, but can be changed in P5.2 (see

digital settings). Amplification factor can

be changed in P9.2 for circuit 1 and in

P9.3 for circuit 2.

Adaptive reference room control

Heat curve is automatically adapted to

the heat requirement. Room temperature

can be increased or decreased by

turning knob d).

The knob must be turned towards +8 if

room temperature is too low. Room

temperature setting range is factory set

at 22 ±8 °C. Knob mid-point can be set in

P5.2 (see digital settings).

Amplification factor can be changed in

P9.3 for circuit 2.

e) Function switch

Heating stopped in circuits 1 and 2.

If circuit 2 is used for hot water

service, heating is stopped in

circuit 1 only.

Time program overridden and

constant control in accordance

with reduced temperature in

circuits 1 and 2. If circuit 2 is used

for hot water service heating, only

circuit 1 is affected.

Automatic changeover between

normal and reduced temperature,

as set on time switch.

This program overridden and

constant control in accordance

with normal temperature in circuits

1 and 2. If circuit 2 is used for hot

water service heating, only circuit

1 is affected.

Manual operation

All control functions stopped.

Valves not activated and all pumps

continously cut-in (see "manual

pump control", page 25.

Valve in circuit 1 can be opened

and closed manually by turning

knob d) fully to the right or to the

left. Valve in circuit 2 can also be

opened and closed manually (see

section "Manual operation",

page 25).

The pump in the heating circuit can

be controlled manually in pushing

the "SET-button", when the setting

switch b) is in position 0 (see

"manual pump control", page 25)

ter settings can be overridden. The

pre-programmed values appear

Heat curve slope can be set within range

0.2 - 3.4. Heat curve is factory-set af 1.8,

but can be overridden with

potentiometer e) in setting >|< to1.8.

If a satisfactory room temperature cannot

be obtained when outdoor temperature is

less than +5 °C, increase slope by

turning knob g). If outdoor temperature is

higher than +5 °C heat curve can be

parallel-displaced by turning knob d).

j) Setting reduced temperature level

If reduced temperature is required the

time switch channels of the respective

circuits are to be set in P8.4.

Factory setting:

Circuit 1: no time control

Circuit 2: no time control

Reduced temperature level can be set at

a fixed value (1 - 8) or at an outdoor

temperature-dependent value (AUTO).

When a room temperature sensor is

connected both circuit 1 (P9.2) and circuit

2 (P9.3) can be selected for reduced

temperature operation. When the setting

is 0 the temperature will not be reduced.

Factory setting of reduced temperature

setting is 5. Each scale graduation

corresponds to about 1 room

temperature degree. In setting >|< , the

potentiometer is overridden to 5.

Reduced temperature

Reduced room temperatures appear from

above figure. Different settings are given

(–2, –4, –6, –8, and AUTO). The figure

shows that the room temperature

reduction is cancelled at outdoor

temperatures -15 °C. This value can be

changed in P1.3 within the range –29 °C

to +10 °C.

h) Hot water service temperature

setting or parallel displacement of

heat curve in circuit 2

Hot water service temperature setting

Hot water service temperature can be

set with potentiometer h) when hot water

service function is selected with

potentiometer i)

Setting range is 30-110 °C.

Mid-setting corresponds to 70 °C.

Factory setting is 50 °C.

Note:

hot water service temperature can

be read in P4.1.

Parallel displacement

When circuit 2 controls heating system,

flow temperature can be increased or

reduced (parallel displacement) with

potentiometer h). The potentiometer

must be turned towards + (clockwise) if

temperature is too low.

Heat curve slope affects magnitude of

parallel displacement. See "Temperature

setting". Setting range is ±8.

i) Hot water service function or setting

heat curve slope in circuit 2

Hot water service function

Hot water service function can be

selected by turning potentiometer fully

counterclockwise, to hot water service

symbol . This cuts out weather

compensation.

Heat curve slope

When circuit 2 is used for heating system

control, heat curve slope can be set

within range 0.4 - 3.4. Heat curve is

factory-set at 1.8, but can be overridden

with potentiometer e) in setting >|< to

1.8.

Position selection

- Position selector

is used when

selecting rows 0 - 9.

- (+) and (–) keys are used for selecting

columns 0 - 6. However, access to

positions in columns 2 - 6 can only be

gained by selecting P0.1 and pressing

SET for 5 seconds. Then, display will

show P0.2 and all positions become

accessible.

- When a particular position is selected,

display shows alternately the position

number, e.g. P1.2, and a particular

value, say 18 °C.

Note: Column 0 displays values only.

Change of value

1) Select required position.

2) Press “SET” once - display flashes.

3) Change value using keys (+) and (–).

4) Press “SET” to store value.

Note

Positions marked # contain up to three

different functions. Values are changed

by choosing one digit at a time.

Press SET and the digit at the very right

will begin to flash. Figure can then be

changed using keys (+) and (–).

When SET is pressed again, middle digit

can be changed. One more press on

SET and the digit at the very left can be

changed. All changes can be stored by

pressing SET. Display will then show

value and position number alternately.
