Emitter type
Depending on the system water volume and the heater emitter type
of the main zone, heating up or cooling down the main zone can
take longer. The setting Emitter type can compensate for a slow
or a quick heating/cooling system during the heat up/cool down
cycle. The target delta T for the main zone depends on this setting.
In room thermostat control, Emitter type influences the maximum
modulation of the desired leaving water temperature, and the
possibility for usage of the automatic cooling/heating changeover
based on the indoor ambient temperature.
It is important to set Emitter type 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:
