EKCBX/H008BBV3
Unit for air to water heat pump system
4PW66983-1C – 08.2011
Pump operation and space heating
When the room thermostat for the floor heating loop (T1) and the fan
coil units (T2) are connected to the indoor unit, the pump (3) will
operate when there is a request for heating from T1 and/or T2. The
outdoor unit will start operating to achieve the target leaving water
temperature. The target leaving water temperature depends on which
room thermostat is requesting heating.
When the room temperature of both zones is above the thermostat
set point, the outdoor unit and pump will stop operating.

NOTICE
■
The request signals for space heating can be
implemented in two different ways (installer choice).
-
Thermo ON/OFF signal from room thermostat
-
Status signal (active/not active) from the mixing
station
■
It is the installers responsibility to make sure no
unwanted situations can occur (e.g. too high water
temperatures towards floor heating loops, etc.)
■
Daikin does not offer any type of mixing station. Dual
set point control only provides the possibility to use
two set points.
■
When only zone A requests heating, zone B will be
fed with water at a temperature equal to the first set
point.
This can lead to unwanted heating of zone B.
■
When only zone B requests heating, the mixing
station will be fed with water at a temperature equal to
the second set point.
Depending on the control of the mixing station, the
floor heating loop can still receive water at a
temperature equal to set point of the mixing station.
■
Be aware that the actual water temperature through
the floor heating loops depends on the control and
setting of the mixing station.
Fragile, handle the unit with care
Keep the unit upright
