Local shift value weather dependent
The local shift value weather dependent field setting is only relevant
in case weather dependent set point (see field setting "[1] Weather
dependent set point (heating operation only)" on page 26) is
selected.
[D-03] Local shift value weather dependent: determines the
shift value of the weather dependent set point around
outdoor temperature of 32°F (0°C).

[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 "Pump operation configuration" on
page 23.
[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.
This function is only valid for EKHBX when space
cooling is selected.
Bottom plate heater control
Applies only to installation with an outdoor unit ERLQ 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.
Functionality of X14A
[F-04] Functionality of X14A: specifies the logic of X14A.
X14A follows the output for the bottom plate heater (1).
Do not change the default value.
Independent from field setting [F-04], the contact
NOTE
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.
