2.4.4 Water tank
[Operation Instructions]
At the commissioning parameter setting page, by touching "Water tank", the control panel will go to the
corresponding setting page, where "Water tank" can be set to "With" or "Without".
When domestic hot water is required, "Water tank" shall be set to "With".
[Notes]
●This setting will be memorized upon power failure.
●This setting will become valid only when the control panel is turned off.
2.4.5 Thermostat
[Operation Instructions]
1.At the commissioning parameter setting page, by touching "Thermostat", the control panel will go to the
corresponding setting page.
2.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 main unit will run based on the mode set by the
thermostat; when it is set to "Without", the main unit will run based on the mode set by the control panel.
[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 main 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 main 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 main 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 main 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 (see Section
2.2.3 and 2.2.4 for more details.)
●When the "Thermostat" is set to "Air + hot water2", there are two kinds of responses for the main units. For
one, if CN26 receives the "OFF" signal (dry contact, 0Vac), the main unit will take the priority to "Hot water". Once
operation conditions for "Hot water" are ready, the main unit will run for "Hot water". Then, when "Hot water" is
satisfied, the main unit will run on the demands of the thermostat. For the other, if CN26 has not received the "OFF"
signal, the main unit will run on the demands of the thermostat.
●The status of the thermostat can be changed only when the control panel is turned off.
●When it has been activated, "Floor debug", "Air removal", and "Emergen.mode" are not allowed to be
activated.
