Key: HKM = Heating circuit module; RRG = Room control module; RT = Room thermostat; CTC = constant temp. circuit;
VTC = variable temperature circuit; TP 1 and 2 = time program 1 or 2 in RRG
Note: If an RRG is not connected, the HKM always controls HC 1
The various options described below can be set by setting the various bits
in program Nos. 555, 558 and 561 (KonfigReg 1, 4 and 7).
Note: Program Nos. 556 and 557 (KonfigRg 2 and 3) should not be
adjusted!

Display on room control module RRG:
Whereby the number following the decimal point indicates the bit (here bit
0) and the value 1 or 0 is indicated by the designation "On" or "Off"!
555.0 Off: Absolute priority (factory setting)
555.0 On: Sliding priority
555.1 On: No priority (parallel operation)
Depending upon the setting, the heating circuit is limited while hot
water is heated:
At the factory, absolute priority is set for the pump heating circuit.
When sliding priority is set and the heating capacity of the
EUROCONDENSE PLUS is not sufficient, the heating circuit is
limited accordingly until the hot water is heated up. Parallel operation
is possible, however, not recommended: This setting applies for all
heating circuits:
555.2 Off: Room thermostat (factory setting)
555.2 On: Timer
Factory setting: room thermostat: The switching state of the room
thermostat contact is decisive for the heat demand. When the contact is
open, the heat demand is inhibited, when the contact is closed, the heat
demand from the room temperature thermostat acts on the
EUROCONDENSE PLUS. The pump is switched on and off according
to the heat demand (with switch-off delay).
If N5 is set to the timer function, in the reduced mode (timer contact
open), the room temperature setting is reduced by the value set in
param. No. 520 (dTrAbsenk) by 10 K (factory setting). The pump runs
in standard mode and in reduced mode except for rapid reduction.
Note: When param. No. 520, code = 0, the heating mode is switched off
completely when the timer contact is open!
Function
Program No 553 Effect of HKM or RRG on HC 1 and HC 2
0 - HKM controls heating circuit 1 (HC 1 of EUROCONDENSE EC)
1 - RRG (heating curve 1 and TP 1) controls HC 1 (CTC)
- HKM (heating curve 2 of EUROCONDENSE PLUS 2) controls HC 2 (VTC)
2 - RRG (heating curve 1 and TP 2) controls HC 1 (CTC)
- HKM (heating curve 1 of EUROCONDENSE PLUS) controls HC 2 (VTC)
10 - HKM (heating curve 1 of EUROCONDENSE PLUS) controls HC 1 (VTC)
- RRG (heating curve 1 and TP 1) controls HC 2 (CTC)
11 - RRG (heating curve 1 and TP 1) controls HC 1 and HC 2
12 - RRG (heating curve 2 and TP 1) controls HC 1 (CTC)
- RRG (heating curve 1 and TP 1) controls HC 2 (VTC)
20 - HKM (heating curve 1 of PEUROCONDENSE PLUS 2) controls HC 1 (CTC)
- RRG (heating curve 2 and TP 2) controls HC 2 (VTC)
21 - RRG (heating curve 1 and TP 1) controls HC 1 (CTC)
Factory setting - RRG (heating curve 2 and TP 2) controls HC 2 (VTC)
22 - RRG (heating curve 2 and TP 2) controls HC 1 and HC 2
