[F] Option setup
Pump operation
The pump operation field setting apply to the pump operation logic
only when DIP switch SS2-3 is OFF.
When the pump operation function is disabled the pump will stop if
the outdoor temperature is higher than the value set by [4-02] or if the
outdoor temperature drops below the value set by [F-01]. When the
pump operation is enabled, the pump operation is possible at all
outdoor temperatures. Refer to "13.3. Pump operation configuration"
on page 29.
■
[F-00] Pump operation: specifies wether the pump operation
function is enabled (1) or disabled (0).
Space cooling permission
■
[F-01] Space cooling permission temperature: defines the
outdoor temperature below which space cooling is turned off.
Bottom plate heater control
Applies only in case the option bottom plate heater kit is installed.
■
[F-02] Bottom plate heater ON temperature: defines the
outdoor temperature below which the bottom plate heater will
be activated by indoor unit in order to prevent ice build-up in
the bottom plate of the outdoor unit at lower outdoor
temperatures.
■
[F-03]
Bottom plate heater hysteresis: defines the
temperature difference between bottom plate heater ON
temperature and the bottom plate heater OFF temperature.

Functionality of X14A
■
[F-04] Functionality of X14A: specifies if the logic of X14A
follows the output signal for the solar kit model (EKSOLHW)
EKHBH/X_AA/AB (0) or if the logic of X14A follows the
output for the bottom plate heater (1).
NOTICE
This function is only valid for EKCBX when space
cooling is selected.

Independent from field setting [F-04], the contact X3-X4
(EKRP1HB) follows the logic of the output signal for the
solar kit model (EKSOLHW). See figure below for the
schematic location of this contact.
