[9‑00] Leaving water temperature compensation value for
heating operation
[9‑01] Leaving water thermistor auto corrective function
This function will take into account the outdoor ambient conditions
and correct the measured value which will be used for the logic.
E.g. when the ambient temperature is high during cooling mode, the
logic will correct the measured value of the leaving water thermistor
to a lower value to take into account influence of high ambient
temperatures in the measurement.
[9-02]
This setting is not applicable.
[9‑03] Leaving water temperature compensation value for
cooling operation
[9-04]
This setting is not applicable.
[A] Option setup
[A-00]
This setting is not applicable.
[A-01]
This setting is not applicable.
[A‑02] Return water temperature undershoot value
This setting makes it possible to set the allowable undershoot when
operating the unit during heating THERMO ON/OFF condition.
The unit will go in THERMO ON only if the return water temperature
(RWT) goes below the setpoint minus the differential temperature:
Thermo ON: RWT<Setpoint–(([A‑02]/2)+1)
The setting [A‑02] has a variability range from 0 to 15 and the step is
1 degree. The default value is 5, meaning that the differential
temperature default value is 3.5.
[A‑03] Leaving water temperature overshoot/undershoot value
This setting makes it possible to set the allowable overshoot
(heating)/undershoot (cooling) when operating the unit during
leaving water control.
[A‑04] Glycol concentration setting
This setting is only applicable for units with a low temperature
cooling option.
When changing this setting, the freeze prevention parameters will be
changed in relation with the glycol concentration.
[A‑04] Description
0 30% glycol, minimum leaving water=0°C
1 40% glycol, minimum leaving water=–10°C
CAUTION
Glycol concentrations lower than the set parameter will
cause the fluid to freeze.
[b]Settings are not applicable
[C] Leaving water temperature limits
This setting is used to limit the selectable leaving water temperature
on the remote controller.
[C‑00] Maximum leaving water setpoint in heating operation
[C‑01] Minimum leaving water setpoint in heating operation
[C‑02] Maximum leaving water setpoint in cooling operation
[C‑03] Minimum leaving water setpoint in cooling operation
This depends on field setting[A‑04].
[C-04]
This setting is not applicable.
[d]Settings are not applicable
[E] Service mode
[E‑00]
This setting is not applicable.
[E‑01]
This setting is not applicable.
[E‑02]
This setting is not applicable.
[E‑03]
This setting is not applicable.
[E‑04] Pump only operation (air purge function)
When installing and commissioning the unit it is very important to
remove all air from the water circuit.
This field setting operates the pump to improve air removal from the
unit without actually operating the unit. The pump will run for
10minutes, stop 2 minutes, etc.
[E‑04] Description
0 (default) Normal operation of the unit
1 Automatic air purge operation during
108minutes
2 Automatic air purge operation during
48minutes
[F] Option setup
[F‑00] Return water temperature overshoot value
This setting makes it possible to set the allowable overshoot when
operating the unit during cooling THERMO ON/OFF condition.
The unit will go in THERMO ON only if the return water temperature
(RWT) goes above the setpoint plus the differential temperature:
Thermo ON: RWT<Setpoint+(([F‑00]/2)+1)
The setting [F‑00] has a variability range from 0 to 15 and the step is
1 degree. The default value is 5, meaning that the differential
temperature default value is 3.5.
7.3 Switching between cooling and
heating
Switching the unit between cooling and heating can be done in 2
different ways. This will depend on how the temperature is
controlled, i.e. based on room temperature or based on leaving
water temperature.
If the unit control is based on room temperature (external room
thermostat or remote controller room thermostat), switching between
cooling and heating is done through the remote controller by pushing
the cooling/heating button.
If the unit control is based on leaving water temperature, we suggest
using the ABC terminals on the outdoor unit (heat pump units only).
The location of the terminals is shown in the following figure.
