Icon appears on the display as well as the corresponding
water temperature set point.
The operation LED lights up.
2 Use the and buttons to set the desired leaving
water temperature.
Temperature range for cooling: 20°C~5°C (leaving water
temperature).
In case the unit has the low temperature cooling option, lower
leaving water temperatures (<5°C) are possible, depending on
the [A-04] Glycol concentration setting. For more information
refer to "[A-04] Glycol concentration setting" on page 23.
Refer to "Programming space" on page 36, "Programming space

setup of the schedule timer function.
5.5. Space heating operation ( ) (for EWYQ units only)
Space heating operation can be controlled on two different ways:
based on room temperature,
based on leaving water temperature (default).
The purpose of each operation and how the configuration is done, is
explained below.
5.5.1. Room temperature control
In this mode, heating will be activated as required by the room
temperature set point. The set point can be set manually or through
the schedule timer.
Selecting space heating operation
1 Use the button to switch ON/OFF space heating ( ).
Icon appears on the display as well as the corresponding
actual room temperature set point.
The operation LED lights up.
2 Use the and buttons to set the desired room
temperature.
Temperature range for heating: 16°C~32°C (room temperature)
In order to avoid overheating, space heating is not operable
when the outdoor ambient temperature rises above a certain
temperature (see operation range).
Refer to "5.9. Programming and consulting the schedule timer"
on page 35 for setup of the schedule timer function.
3 Use the and buttons to select the leaving
water temperature which you want to be used to heat up your
system (for detailed information see "5.5.2. Leaving water
temperature control (default)" on page 32).
Automatic setback function
Setback function provides the possibility to lower the room
temperature. The setback function can for instance be activated
during the night because the temperature demands during night and
day are not the same.
The setback function is configured through field settings. Refer to the
chapter "6. Field settings" on page 40 for a detailed description how
to set one or more field settings.
[2-00] Status: defines whether the setback function is turned ON
(1) or OFF (0)
[2-01] Start time: time at which setback is started
[2-02] Stop time: time at which setback is stopped
[5-03] Room setback temperature
A Normal room temperature set point
B Room setback temperature

INFORMATION
When an external room thermostat is installed, the
thermo ON/OFF is determined by the external room
thermostat. The remote controller is then operated in
the leaving water control mode and is not functioning
as a room thermostat.
The remote controller ON/OFF status always has
priority over the external room thermostat!
Setback operation and weather dependent set point
are not available in cooling operation.
INFORMATION
When using room temperature control, space heating
operation based on room temperature will have priority
over leaving water control.
Note that it is possible that the leaving water temperature
becomes higher than the set point if the unit is controlled
by room temperature.
INFORMATION
Remark that the icon will be flashing during setback
operation.
By default the setback function is enabled.
The setback function can be combined with the
automatic weather dependent set point operation.
Setback function is an automatic daily scheduled
function.
