1. From the Auxiliary settings menu highlight Freeze Stat Function.
2. Press CONFIRM. The freeze stat function screen will be displayed.
3. Use buttons F3 and F4 to adjust the minimum outdoor ambient temperature at which freeze stat
function will begin to operate, (3 - 20 °C).
4. If (**) is chosen freeze stat function is deactivated.
Simultaneous Operation
For periods of very low outside temperature this mode can be used. Simultaneous operation allows both DHW
and space heating to run together by using the heat pump and/or booster heater to provide space heating whilst
only the immersion heater provides heating for DHW. This operation is only available if BOTH a DHW tank AND
immersion heater are present on the system.
1. From the Operation settings menu use F1 and F2 buttons to scroll through the list until Simultaneous
operation is highlighted.
2. Press CONFIRM.
3. Simultaneous operation screen is displayed.
4. To switch simultaneous operation ON/OFF press F1.
5. To alter the temperature at which simultaneous operation starts use F3 and F4.
Note:
Range of outdoor ambient temperature is −15°C to 10°C (default −15°C). The system shall automatically return to
routine operation. This will happen when the outdoor ambient temp rises above the selected temp for this specific
mode of operation.
Cold Weather Function
For extremely low outdoor ambient temperature conditions when the heat pump's capacity is restricted, the heating
or DHW is provided only by the electric booster heater (and immersion if present). This function is intended for use
during extreme cold periods only. Extensive use of direct electrical heaters ONLY will result in higher electric usage
and may reduce working life of heaters and related parts.
1. From the Operation settings menu use F1 and F2 buttons to scroll through the list until Cold weather
function is highlighted.
2. Press CONFIRM.
3. Cold weather function screen is displayed.
4. To switch Cold weather function ON/OFF press F1.
5. To alter the temperature at which heater switching function starts use F3 and F4.
Note:
Range of outdoor ambient temperature is −15°C to −10°C (default −15°C). System shall automatically return to
routine operation. This will happen when the outdoor ambient temp rises above the selected temp for this specific
mode of operation.
Flow Temperature Range (Heating)
This function allows operational setting of flow temperature range from the Ecodan
which the FTC4 collects and processes data for the auto adaptation mode. The lower and upper limits entered
here will dictate the flow temperature range at which the system will be able to operate.
