is heating demand as the leaving
water temperature has not yet reached
the desired temperature yet. When
thermo OFF condition occurs, the
pump runs every 3 minutes to check
the water temperature and demand
heating if necessary. Remark: Sample

▪ 1 Cooling only
▪ 2 Heating only
▪ 3 Reversible
Pump limitation
The pump speed limitation for the main zone [9‑0E] and additional
zone [9‑0D] defines the maximum pump speed. In normal
conditions, the default setting should NOT be modified. The pump
speed limitation will be overruled when the flow rate is in the range
of the minimum flow (error 7H).
# Code
[4.7] [9-0D] Pump limitation Additional zone:
▪ 0: No limitation
▪ 1~4: General limitation. There is
limitation
required delta T control and comfort
are NOT guaranteed.
▪ 5~8: Limitation when no actuators.
When there is no heating output, the
pump speed limitation is applicable.
When there is heating output, the
pump speed is only determined by
delta T in relation to the required
capacity. With this limitation range,
delta T is possible and the comfort is
guaranteed.
