Antifreeze Function - Resol DeltaTherm HC mini Handbuch Für Den Fachhandwerker

If the Correction mode Day / Off, Room / Off or Outdoor / Off is selected, the
heating circuits and the backup heating are completely switched off during night op-
eration. If the system has a store, the Starting time can be used for activating the
backup heating before the day operation in order to heat the store to a sufficiently
high temperature.
At first, backup heating is activated and can be temporarily deactivated.
Remote access
With the parameter Remote access different types of remote access to the con-
troller can be activated.
The following types of remote access are possible:
Remote control: A device which allows manual adjustment of the heating curve,
thus influencing the set flow temperature.
Î In order to use a remote control, set the corresponding input to RTA.
Room control unit: A device incorporating a remote control as well as an addi-
tional operating mode switch.
Î In order to use a room control unit, set the corresponding input to BAS.
The operating mode switch of the room control unit is used for adjusting the op-
erating mode of the controller. If a room control unit is used, the operating mode
can be adjusted by means of the room control unit only. The controller menu only
allows the activation of the operating mode Holiday.
In the sensor selection menu, only outputs which have previously been selected as
the input for remote access in the Inputs / Outputs menu will be available.
Remote access with the app: In addition to the wireline possibilities of remote
access, an app can be used as well.
Î In order to use an app, adjust the corresponding input to VF1.
If you use an app, the operating mode can be adjusted in the controller menu as
well as in the app.

Antifreeze function

The antifreeze function of the heating circuit can be used to temporarily activate
an inactive heating circuit during sudden temperature drop in order to protect it
against frost damage.
The temperature at the allocated antifreeze sensor Sen. Frost is monitored. If the
temperature falls below the adjusted antifreeze temperature TFrost, the heating
circuit will be activated until the antifreeze temperature is exceeded by 2 K, but at
least for 30 min.
