The screed drying programme will start immediately and continue for the
selected number of days.
At the end of the programme, the selected operating mode will restart.

The on/off or modulating thermostat is connected to the R-Bus terminals
on the EHC–05 PCB or the optional SCB-10 PCB.
The PCBs are delivered with a bridge on the R-Bus terminals.
The R-Bus input can be configured to add the flexibility of using several
types of on/off thermostat or OpenTherm (OT).
1. Configure the parameters for the circuit concerned:
On
Description
Configuration of the on/off input contact direction for heating mode.
Closed (default value): heating demand when contact is closed
Open: heating demand when contact is open
Reversal of the direction of the logic in cooling mode compared to heating mode
No (default value): cooling demand uses the same logic as the heating demand
Yes: cooling demand uses the reverse logic to the heating demand

CP691, CP693)

7.3.15
The AC thermostat (air conditioning) is always connected to the R-Bus
and BL1 terminals on the EHC–05 PCB. The AC thermostat is only
compatible with configurations with a single heating circuit.
Priority will be given to the AC thermostat input over the other Summer/
Winter modes (Auto/Manual).
The PCBs are delivered with a bridge on the R-BUS terminals.
