Emitter type
Depending on the system water volume and the heater emitter type
of the main zone, the heat up or cooling down of the main zone can
take longer. This setting can compensate for a slow or a quick
heating/cooling system during the heat up/cool down cycle (cooling
only with EKHVCONV2 installed).
The target delta T for the main zone will depend on this setting.
Target delta T control is only possible in case only 1 zone is active.
Pump control will be different when both zones are active.
In room thermostat control, this setting will influence:
▪ the maximum modulation
temperature.
▪ the possibility for usage of the automatic cooling/heating
changeover based on the indoor ambient temperature (only with
EKHVCONV2 installed).
Therefore it is important to set this correctly and in accordance with
your system layout.

The setting of the emitter type has an influence on the space heating
setpoint range and the target delta T in heating as follows:
