0 Service
code
[15]
-
Access to installer settings. The service code must be entered
(=15).
1
System type
1
0 = standard
1 = heating only ope indirect hot water tank
(Note: Factory setting is 1. Do not change this setting)
2 = n/a
3 = n/a
2
CH pump continuous
0
0 = pump normal with overrun
1 = pump on continuously; 2 = n/a
3
Set CH power
50
Setting maximum CH load, range c – 99% (or 100 if button
pressed again when 99 reached)
4
Set max power
50
Setting maximum power (can be increased to 99)
5
Min. supply temperature of
the control line
25
Setting range 10°C to 25°C (Weather-dependent control)
6
Min. outside temperature of
the control line
-7
Setting range -9°C to 10°C (Weather-dependent control)
7
Max. outside temperature of
the control line
25
Setting range 10°C to 30°C (Weather-dependent control)
8
CH pump overrun time after
CH operation
1
Setting range 0 - 15 minutes
9
CH pump overrun time after
external HW tank operation
2
Setting range 0 - 15 minutes (n/a)
A
Position of three-way or two-
way valve
0
0 = output signal given for CH operation (n/a)
1 = output signal given for HW tank operation (n/a)
b (n/a)
C
Step modulation
1
0 = step modulation off during CH operation
1 = step modulation on during CH operation
c
Min speed in CH operation
25
Setting range 25 to 50% of fan speed (Note: For propane or
for appliances with flue non-return valve, set 40)
d (n/a)
E
Min. supply temperature
during OT demand
10
Setting range 10°C to 60°C. (OT = OpenTherm stat)
E.
OT response
0
0 = Ignore the OT demand if it is lower than parameter E
1 = Set the value at parameter E, if the OT demand is lower
2 = OT device is switched off and the room stat functions as
an on/off switch, with the supply temp set at the appliance.
F
Starting speed CH
70
Setting range 50 to 99% (Note: For propane, set 50).
This parameter sets the fan speed for ignition and post purge.
F.
Starting speed DHW
(not applicable to
InterSystem)
70
Setting range 50 to 99% (Note: For propane, set 50).
This parameter sets the fan speed for ignition and post purge
h
Max. fan speed
45
Setting range 40 to 50 (40 = 4000 rpm, 50 = 5000 rpm) The
absolute maximum speed can be set through this parameter.
n (n/a)
o
Heating delay after hw use
0
(n/a) (0 to 15 mins).
P
Minimum switch off time
during CH operation
5
Setting range 0 to 15 minutes (anti cycling function)
