Setpoint range
You can limit the range of the leaving water temperature for the main leaving
water temperature zone. The purpose of this setting is to prevent a wrong (i.e. too
hot or too cold) leaving water temperature. Therefore, the available desired
heating temperature range can be configured.
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.
INFORMATION
Only for EHVZ: If the indoor unit is connected to a high temperature emitter system,
and simultaneous demand exists on both emitter zones, and if the high emitter
system leaving water setpoint is chosen bigger than 60°C in the complete operation
range, there can be an increased power consumption.
NOTICE
▪ When adjusting the leaving water temperature ranges, all desired leaving water
temperatures are also adjusted to guarantee they are between the limits.
▪ Always balance between the desired leaving water temperature with the desired
room temperature and/or the capacity (according to the design and selection of
the heat emitters). The desired leaving water temperature is the result of several
settings (preset values, shift values, weather-dependent curves, modulation). As a
result, too high or too low leaving water temperatures could occur which lead to
overtemperatures or capacity shortage. By limiting the leaving water
temperature range to adequate values (depending on the heat emitter), such
situations can be avoided.
Example: In heating mode, leaving water temperatures must be sufficiently higher
than the room temperatures. To avoid that the room cannot heat up as desired,
set the minimum leaving water temperature to 28°C.
# Code Description
Leaving water temperature range for the main leaving water temperature zone (=
the leaving water temperature zone with the lowest leaving water temperature in
heating operation)
[2.8.1] [9-01] Heating minimum:
▪ 15°C~37°C
[2.8.2] [9-00] Heating maximum:
▪ [2‑0C]=2 (emitter type main zone = radiator)
37°C~65°C
▪ Else: 37°C~55°C
Control
Define how the operation of the unit is controlled.
