Glycol Adding glycol to the water circuit is recommended to guarantee frost protection in the
event of a power failure. If glycol has been added to the system, the RoCon controller
setting must be adapted accordingly.
0: no glycol added
1: glycol added

Function Heating
Rod
Setting regarding whether an additional heat generator (WEZ) for hot water preparation
and heating support is available (see chap.
3.6.7).
0: no additional WEZ
1: optional backup heater
2: alternative WEZ undertakes hot water preparation and heating support
3: alternative WEZ 1 undertakes hot water preparation and alternative WEZ 2 under-
takes heating support
N E 0 - 3 1 1
Emergency BUH If the heat pump fails, the backup heater can be used as emergency heating, and can
undertake all heating requirements either automatically or non-automatically.
0: no automatic emergency operation
1: automatic emergency operation
E E 0 - 1 0 -
HZU Heating support from hot water storage tank if minimum temperature is exceeded (see
chap.
3.6.8 and parameter [TDiff-DHW CH Support]).
Off: no heating support
On: heating support function active

Equilibrium Func. The bi-valence function is only relevant to operation of the optional heater booster due
to a backup requirement (room heating mode).
Off: operation of the backup heater is always possible.
On: backup heater is only released if the temperature set in the parameter [Equilibrium
Temp] is undershot.
N E Off

SMART GRID Evaluation of the SG signal (see chap. 3.4.12).
0: Smart Grid function not active, SG signal is not evaluated.
1: depending on utility company signal, the heat pump is shut off (no frost protection func-
tion - see chap. 3.6.5) or operated at higher temperatures.
N E 0 - 1 0 -
Mode SG Only if [SMART GRID] parameter = 1:
Used for a possible increase in the target temperature in the case of a Smart Grid switch-
on command.
0: comfort (target hot water temperature increase by 5 K)
1: standard (target feed temperature increase by 2 K and target hot water temperature
increase by 5
K)
2: eco (target feed temperature increase by 5 K and target hot water temperature in-
crease by 7 K)
N E 0 - 2 1 1
HT/NT Function Setting regarding which heat sources are switched off if the peak signal output by the util-
ity company (EVU) is received in the case of an off-peak mains connection.
0: deactivated (no effect)
1: refrigerant compressor is switched off
2: refrigerant compressor and backup heater are switched off
3: everything is switched off (no frost protection function - see chap. 3.6.5)
N E 0 - 3 0 1
HT/NT Contact Definition of whether the HT/NT input is evaluated as a normally closed contact or a nor-
mally open contact.
0: normally open contact (switching contact closed = peak)
1: normally closed contact (switching contact closed = off-peak)
N E 0 - 1 0 -
Room thermostat Configuration of a room thermostat with potential-free contacts connected to ROTEX
HPSU monobloc compact connection J16.
Off: Deactivated
On: (only if parameter [Interlink fct] = Off)
Evaluation of the heating and cooling switching contacts at plug connection
J16 on the RoCon BM1 printed circuit board (only if none of the "Standby", "Reduc-
ing", "Summer", "Vacation", "Holiday" or "Screed" operating modes are active):
a) Closed heating switching contact: operating mode is switched to "Heating".
Priority if both switching contacts are closed.
b) Closed cooling switching contact: operating mode is switched to "Cooling".
c) Open contacts: only frost protection active.
