Heating

In this menu, all adjustments for the heating circuit can be made.
Additionally, the screed drying function can be activated and adjusted.
8.1

Shared relays

In this menu, 1 shared relay can be activated and adjusted. Further options such
as a minimum and a maximum limitation for boiler protection are also available.
The shared relay will be available for selection under Virtual in the relay allocation
channel of the Heating circuit menu.
Note:
Activate and adjust the shared relay first. It will then be available in the
heating circuit.
Demand
The demand can be carried out by means of a relay and/or a 0-10 V output. If both
the Relay and the 0-10 V option are activated, the demand will use both outputs
in parallel.

Relay option

If the Relay option is activated, the sub-menu Relay appears, in which a relay can
be allocated to the demand.
The options Boiler protection min and Boiler protection max can be activat-
ed for the demand via a relay, allowing temperature-dependent control of the boiler
demand. For this purpose, a boiler sensor (Sensor Boiler) is required.
The Boiler pr. min option is used for protecting an older type boiler against cool-
ing. If the temperature falls below the adjusted minimum temperature, the allocated
relay is energised until the minimum temperature is exceeded by 2 K.
The Boiler pr. max option is used for protecting an older type boiler against
overheating. If the adjusted maximum temperature is exceeded, the allocated relay
is switched off until the temperature falls by 2 K below the maximum temperature.
