The setting
Emitter type
can compensate for a slow or a quick heating/cooling
system during the heat up/cool down cycle. In room thermostat control, the
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 the emitter type correctly and in accordance with your system
layout. The target delta T for the main zone depends on it.
