If... Then...
Space heating/cooling is ON, the
external room thermostat is
"Thermo OFF", the operation
mode is "heating" and the
outdoor temperature drops below
4°C The unit will supply leaving water
to the heat emitters to heat up
the room again, and the leaving
water temperature setpoint will
be lowered.
Room thermostat control ([C‑07]=2)
During room thermostat control, room frost protection is guaranteed
if it is enabled. When room frost protection [2‑06] is activated and the
room temperature drops below the room antifrost temperature [2‑05],
the unit will supply leaving water to the heat emitters to heat up the
room again.
# Code Description
[1.4.1] [2-06] Activation:
▪ 0 No: Antifrost functionality is OFF.
▪ 1 Yes: Antifrost functionality is on.
[1.4.2] [2-05] Room setpoint 4°C~16°C
INFORMATION
When the user interface used as room thermostat is
disconnected (due to miswiring, damage of the cable), then
room frost protection is NOT guaranteed.
NOTICE
If Emergency is set to Manual ([9.5]=0), and the unit is
triggered to start emergency operation, the unit will stop
and need to be recovered manually via the user interface.
To recover operation manually, go to the Malfunctioning
main menu screen, where the user interface will then ask
you to confirm emergency operation before starting.
Room frost protection is active even if the user does NOT
confirm emergency operation.
Setpoint range
ONLY applicable in room thermostat control. To save energy by
preventing overheating or undercooling the room, you can limit the
range of the room temperature, both for heating and/or cooling.
NOTICE
When adjusting the room temperature ranges, all desired
room temperatures are also adjusted to guarantee they are
between the limits.
# Code Description
[1.5.1] [3-07] Heating minimum
[1.5.2] [3-06] Heating maximum
[1.5.3] [3-09] Cooling minimum
[1.5.4] [3-08] Cooling maximum
Room sensor offset
ONLY applicable in case of room thermostat control. You can
calibrate the (external) room temperature sensor. It is possible to
give an offset to the room thermistor value measured by the user
interface used as room thermostat or by the external room sensor.
The settings can be used to compensate for situations where the
user interface used as room thermostat or the external room sensor
CANNOT be installed on the ideal installation location (see
"5.7 Setting up an external temperature sensor" on page 16 ).
# Code Description
[1.6] [2-0A] Room sensor offset (user interface used
as room thermostat): Offset on the actual
room temperature measured on the user
interface used as room thermostat.
▪ –5°C~5°C, step 0.5°C
[1.7] [2-09] Room sensor offset (external room
sensor option): ONLY applicable if the
external room sensor option is installed
and configured.
▪ –5°C~5°C, step 0.5°C
8.4.3 Main zone
Cooling settings are only applicable in case a conversion
kit (EKHVCONV2) is installed.
Setpoint screen
You can set the leaving water temperature for the main zone using
the setpoint screen. For more information about how to do this, see
"8.3.5 Setpoint screen" on page 39 .
Schedule
Indicates if the desired leaving water temperature is according to a
schedule. Influence of the LWT setpoint mode [2.4] is as follows:
▪ In Fixed LWT setpoint mode, the scheduled actions consist of
desired leaving water temperatures, either preset or custom.
▪ In Weather dependent LWT setpoint mode, the scheduled actions
consist of desired shift actions, either preset or custom.
# Code Description
[2.1] N/A Schedule
▪ 0: No
▪ 1: Yes
Heating schedule
You can set the main zone heating temperature schedule using the
schedule screen. For more information about this screen, see
"8.3.8 Schedule screen: Example" on page 40 .
Cooling schedule
You can set the main zone cooling temperature using the schedule
screen. For more information about this screen, see
"8.3.8 Schedule
screen: Example" on page 40 .
Setpoint mode
In Fixed mode, the desired leaving water temperature does NOT
depend on the outdoor ambient temperature.
In WD heating, fixed cooling mode, the desired leaving water
temperature:
▪ depends on the outdoor ambient temperature for heating
▪ does NOT depend on the outdoor ambient temperature for cooling
In Weather dependent mode, the desired leaving water temperature
depends on the outdoor ambient temperature.
# Code Description
[2.4] N/A Setpoint mode
▪ 0: Fixed
▪ 1: WD heating, fixed cooling (only with
EKHVCONV2 installed)
▪ 2: Weather dependent
When weather dependent operation is active, low outdoor
temperatures will result in warmer water and vice versa. During
weather dependent operation, the user has the possibility to shift the
water temperature up or down by a maximum of 10°C.
