Description
[2.7]
[2‑0C]
Emitter type
:
▪
0:
Underfloor heating
▪
1:
Fancoil unit
▪
2:
Radiator
The setting
Emitter type
influences the space heating setpoint range and the
target delta T in heating as follows:
Emitter type
Main
zone
Space heating setpoint
range [9‑01]~[9‑00]
Target delta T in heating
[1‑0B]
0:
Underfloor
heating
Maximum 55°C
Variable (see [2.B.1])
1:
Fancoil unit
Maximum 65°C
Variable (see [2.B.1])
2:
Radiator
Maximum 65°C
Variable (see [2.B.1])
NOTICE
The maximum setpoint in space heating depends on the emitter type as can be seen
in above table. If there are 2 water temperature zones, then the maximum setpoint
is the maximum of the 2 zones.
NOTICE
NOT configuring the system in the following way can cause damage to the heat
emitters. If there are 2 zones, it is important that in heating:
▪
the zone with the lowest water temperature is configured as the main zone, and
▪
the zone with the highest water temperature is configured as the additional zone.
NOTICE
If there are 2 zones and the emitter types are wrongly configured, water of high
temperature can be sent towards a low temperature emitter (underfloor heating). To
avoid this:
▪
Install an aquastat/thermostatic valve to avoid too high temperatures towards a
low temperature emitter.
▪
Make sure you set the emitter types for the main zone [2.7] and for the
additional zone [3.7] correctly in accordance with the connected emitter.
Setpoint range
To prevent a wrong (i.e. too hot or too cold) leaving water temperature for the
main leaving water temperature zone, limit its temperature range.
NOTICE
In case of a floor heating application it is important to limit the:
▪
maximum leaving water temperature at heating operation according to the
specifications of the floor heating installation.
▪
the minimum leaving water temperature at cooling operation to 18~20°C to
prevent condensation on the floor.
