At the submenu page, “Solar setting” can be set to “With” or “Without”.
At the submenu page, the “Solar heater” can be set to “On” or “Off”.

Notes

This setting can be done no matter if the unit is turned on or off.
This setting is allowed only when the water tank is available. When the water tank is unavailable, this setting will be reserved.
It will be memorized upon power failure.

Water Tank

Operation Instructions
At the commissioning parameter setting page, by touching “Water tank”, the control panel will access to the corresponding setting page, where “Water tank” can be set to “With” or “Without”.

Notes

This setting will be memorized upon power failure.
This setting will become valid only when the unit is turned off.

Thermostat

Operation Instructions

At the commissioning parameter setting page, by touching “Thermostat”, the control panel will access to the corresponding setting page.
At the “Thermostat” setting page, it can be set to “Air”, “Without”, “Air + hot water” and “Air + hot water2” When it is set to “Air”. “Air + hot water” or “Air + hot water2”, the unit will run based on the mode set by the thermostat; when it is set to “Without”, the unit will run based on the mode set by the control panel. For mini chillers, it can be set to “On” or “Off”.
For mini chillers, it can be set to “On” or “Off”.

Notes

When “Water tank” is set to “Without”, the “Air + hot water” or “Air + hot water2” mode is unavailable.
When “Floor debug” and “Emergen.mode” have activated, function of the thermostat will be invalid.
When “Thermostat” is set to “Air”, “Air + hot water” or “Air + hot water2”, “Temp.timer” will be deactivated automatically and the unit will run based on the mode set by the thermostat. Meanwhile, mode setting and On/Off operation by the control panel will be ineffective.
When “Thermostat” is set to “Air”, the unit will run based on the setting of the thermostat.
When “Thermostat” is set to “Air + hot water”, when the thermostat is turned off, the unit can still perform the “Hot water” mode. In this case, the ON/OFF icon at the homepage does not indicate the running status of the unit. Running parameters are available at the parameter viewing pages.
When “Thermostat” is set to “Air + hot water”, operation priority can be set by the control panel
When the “Thermostat” is set to “Air + hot water?”, there are two kinds of responses for the units. For one, if CN26 receives the “OFF” signal (dry contact, OVac), the unit will take the priority to “Hot water”. Once operation conditions for “Hot water” are ready, the unit will run for “Hot water”. Then, when “Hot water” is satisfied, the unit will run on the demands of the thermostat. For the other, if CN26 has not received the “OFF” signal, the unit will run on the demands of the thermostat.
The status of the thermostat can be changed only when the unit is turned off.
When it has been activated, “Floor debug”, “Air removal”, and “Emergen.mode” are not allowed to be activated.
This setting will be memorized upon power failure.

Other Thermal

Operation Instructions

At the commissioning parameter setting page, by touching “Other thermal”, the control panel will access to the corresponding setting page.
At the “Other thermal” setting page, “Other thermal” can be set to “With” or “Without”, “T-Other switch on” can be set to the desired value. When “Other thermal” is set to “With”, it is allowed to set the operating mode for the backup thermal source.

Notes

This setting will be memorized upon power failure.
There are three working logics for it.

Logic 1

The set point of other thermal should be equal to that of “WOT-Heat” in “Heat” mode and “Heat + hot water” mode; The set point should be the smaller one between “T-Water tank” +5°C and 60°C in “Hot water” mode.
The water pump for other thermal must be always active under the “Heat” mode.
Under the “Heat” mode, the 2-way valve will be controlled based on the setting of the control panel. During heating operation, the water pump of the heat pump unit will be stopped; however, during standby status, the water pump will start but the other thermal will stop.

Under the “Hot water” mode, the 3-way valve will switch to the water tank, the water pump of the heat pump will always stop but the other thermal will start. Under the “Heat + Hot water” mode, the other thermal only works for space heating, and the electric heater of the water tank works for water heating. In this case, the 2-way valve is controlled based on the setting of the control panel, and the 3-way valve will always stop. During heating operation, the water pump of the heat pump unit will be stopped; however, during standby status, the water pump will start.

Logic 2

The set point of other thermal should be equal to that of “WOT-Heat” and both are or lower than 60 C in “Heat” mode and “Heat + hot water”mode; The set point should be the smaller one between “T-Water tank” +5°C and 60°C in “Hot water” mode.
The water pump for other thermal must be always active under the “Heat” mode.
Under the “Heat” mode, the 2-way valve will be controlled based on the setting of the control panel. During heating operation, the water pump of the heat pump unit will be stopped; however, during standby status, the water pump will start but the other thermal will stop.

Under the “Hot water” mode, the 3-way valve will switch to the water tank, the water pump of the heat pump will always stop but the other thermal will start.

Under the “Heat + Hot water” mode (“Heat” takes the priority), the other thermal only works for space heating, and the electric heater of the water tank works for water heating. In this case, the 2-way valve is controlled base d on the setting of the control panel, and the 3-way valve will always stop. During heating operation, the water pump of the heat pump unit will be stopped; however, during standby status, the water pump will start. Under the “Heat + Hot water” mode (“Hot water” takes the priority), the other thermal works for space heating and water heating. The other thermal will work for water heating firstly, after reached “-water tank”, other thermal turns to space heating.

Logic 3
The heat pump will only send a signal to other thermal, but all the logic of control must be “stand alone”.
