Field Setting ESIE09-08A
102 Test Operation
[6] Option setup

[6-00] Domestic hot water tank option
If the domestic hot water tank is installed, its operation must be enabled by field setting. Default [6-
00] = 0 which means no tank is installed. Set [6-00] to 1 if the optional domestic hot water tank is
installed.
Note : When enabling the domestic hot water tank option be aware that the advised default settings become
active:

[1-00] = 1 = automatic night storage

[4-00] = 1 = disinfection function

[6-01] External room thermostat option
If the optional external room thermostat is installed, its operation must be enabled by field setting.
Default [6-01] = 0, which means no external room thermostat is installed. Set [6-01] to 1 if the
optional external room thermostat is installed.
The external room thermostat only gives an ON/OFF signal to the heat pump based on the room
temperature. Because it does not give continuous feedback information to the heat pump, it is
supplementary to the remote controller room thermostat function. To have a good control of the
system and avoiding frequent ON/OFF it is advised to use the automatic weather dependent set point
operation.
Note : By using an external room thermostat, the smart logic of the standard remote controller is overruled.

[6-02] Heater kit
Once installed, you can activate the heater kit by changing field setting [6-02]=1.
From that moment on, the heat pump system will take the heater kit into account whilst deciding
operation. When the heater is actually operating, the heater symbol is shown on the remote controller.
There is no step 1-2 indication.
For more information see “Part 9 - External Backup Heater Kit” on page 255.

[6-03] Solar support
For more information refer to the EKHWP installation manual.

[6-04] Benefit kWh rate power supply mode
If benefit kWh rate power supply is used, the mode must be selected. Default [6-04] = 0 which means
no benefit kWh rate power supply is used.
Set [6-04] to 1 to use benefit kWh rate power supply mode 1 (normally closed contact which will
open when the power supply is interrupted), or set [6-04] to 2 to use benefit kWh rate power supply
mode 2 (normally opened contact which will close when the power supply is interrupted).
