Set weather-dependent heating in [9.l]
Overview field settings :
▪ [1-00]: Low outdoor ambient temperature. –
40°C~+5°C
▪ [1-01]: High outdoor ambient temperature.
10°C~25°C
▪ [1-02]: Desired leaving water temperature
when the outdoor temperature equals or drops
below
the low ambient temperature.
[9‑01]°C~[9‑00]°C
Note: This value should be higher than [1‑03]
as for low outdoor temperatures warmer water
is required.
▪ [1-03]: Desired leaving water temperature
when the outdoor temperature equals or rises
above
the high ambient temperature.
[9‑01]°C~min(45, [9‑00])°C
Note: This value should be lower than [1‑02] as
for high outdoor temperatures less warm water
is required.
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.
Target delta T control is only possible in case only 1 zone is active. Pump control
will be different when both zones are active.
