[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 "8.3. Pump operation configuration"
on page 24.
■ [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.
INFORMATION
This function is only valid for RKHBX when space
cooling is selected.
Bottom plate heater control
Applies only to installation with an outdoor unit RRLQ or 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
temperature difference between bottom plate heater ON
temperature and the bottom plate heater OFF temperature.

CAUTION
The bottom plate heater is controlled via X14A. Make sure
[F-04] is correctly set.
INFORMATION
The bottom plate heater at RRLQ_CA is controlled
internally by the outdoor unit pcb. The field settings [F-02]
and [F-03] are not applicable for this unit.

Functionality of X14A
■ [F-04] Functionality of X14A: specifies if the logic of X14A
follows the output signal for the solar kit model RKHBH/
X_AA/AB (0) or if the logic of X14A follows the output for the
bottom plate heater (1).
INFORMATION
Independent from field setting [F-04], the contact X3-X4
(EKRP1HB) follows the logic of the output signal for the
solar kit model. See figure below for the schematic location
of this contact.
