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

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.

SMART GRID
Evaluation of the SG signal (see chap. 3.4.12).
0: Smart Grid function not active, SG signal is not evaluated.

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.

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.
