Code
Description
[9.C.3]
[C-03]
Bivalent ON temperature: Defines the
outdoor temperature below which the
permission signal for the auxiliary boiler
is active (X1 and X2 on EKRP1HB is
closed) and space heating by indoor unit
is stopped.
[9.C.4]
[C-04]
Hysteresis: Defines the temperature
difference between the ON temperature
and the OFF temperature.

Possibility 2: Based on the outdoor temperature and energy prices
The installer can set a temperature range [C‑04]. Depending on the
energy prices, a calculated point T
calc
varies within a range between
[C‑03] and [C‑03]+[C‑04]. It is recommended to choose [C‑04] bigger
than the default value to have an optimal operation when choosing
possibility 2.

INFORMATION
Electricity price can only be set when bivalent is ON
([9.C.1] or [C-02]). These values can only be set in menu
structure [7.5.1], [7.5.2] and [7.5.3]. Do NOT use overview
settings.
When the outdoor temperature reaches below the T
calc
point, then
the permission signal for the auxiliary boiler becomes active. To
prevent too much switching, there is a hysteresis of 3°C.

Description
[9.D]
[C–09]
Alarm output: Indicates the logic of the
alarm output on the digital I/O PCB
during malfunctioning.
▪ 0 Abnormal: The alarm output will be
powered when an alarm occurs. By
setting this value, a distinction is made
between the detection of an alarm,
and the detection of a power failure.
▪ 1 Normal : The alarm output will NOT
be powered when an alarm occurs.
See also table below (Alarm output
logic).

Auto restart
Auto restart
When power returns after a power supply failure, the auto restart
function reapplies the remote controller settings at the time of the
power failure. Therefore, it is recommended to always enable the
function.
If the preferential kWh rate power supply is of the type that power
supply is interrupted, always enable the auto restart function.
Continuous indoor unit control can be guaranteed independent of the
preferential kWh rate power supply status, by connecting the indoor
unit to a normal kWh rate power supply.

Power saving function
Power saving function
Defines whether the outdoor unit power supply can be interrupted
(internally by indoor unit control) during stand-still conditions (no
space heating/cooling nor domestic hot water demand). The final
decision to allow power interruption of the outdoor unit during
standstill depends on the ambient temperature, compressor
conditions and minimum internal timers.
To enable the power saving function setting, [E‑08] needs to be
enabled on the user interface.
