Emitter type
Heating up the main zone can take longer. This depends on:
▪ The water volume of the system
▪ The heater emitter type of the main zone
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, 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 target delta T for the main zone depends on it.
Description
Set weather-dependent heating:
Note: There are 2 methods to set the weather
dependent curve. See "10.5.2 2-points
4
curve" [ 144] and "10.5.3 Slope-offset
4
curve" [ 145]. Both curve types require 4 field
settings to be configured according to the figure
below.

Note: This value should be higher than [1‑03]
as for low outdoor temperatures warmer water
is required.
