4. Room Thermistor
Indoor
Outdoor
Connect fl oor heating or radiator directly to Tank Unit.
Remote controller is installed on Tank Unit.
Install separate external room thermistor (specifi ed by Panasonic) in the room where fl oor heating is installed.
This is an application that uses external room thermistor to control room temperature.
There are 2 kinds of circulation water temperature setting method.
Direct: Set direct circulation water temperature (fi xed value)
Compensation curve: Set circulation water temperature depends on outdoor ambient temperature
In case of Room thermostat or Room thermistor, compensation curve can be set.
In this case, compensation curve is shifted according to the thermo ON/OFF situation.
•
(Example) If room temperature increasing speed is;
very slow shift up the compensation curve
very fast shift down the compensation curve
(NOTE)
•
Zone 1 should always set with higher water temperature than zone 2. If not set correctly, water temperature fl ow into zone 1 water circuit
may higher than the set temperature.
•
Please adjust fl ow rate of zone 1 and zone 2 to be in balance by setting zone 1 only and zone 2 only water fl ow to equivalent water fl ow.
If it is not adjusted correctly, it may affects the performance. (eg. If zone 2 pump fl ow rate is high, there is possibility that no hot water
fl owing to zone 1)
a) Zone 1 only water fl ow can be adjusted and check through Service Setup (Pump Max Speed)
b) Zone 2 only water fl ow can be adjusted by knot of pump and check through Maintenance Menu (Actuator Check) -> Activate Zone 2
pump and Switch Zone 2 Mixing Valve to "+" direction.
Examples of installations
Floor heating 1 + Floor heating 2
Indoor
Outdoor
Connect two fl oor heating circuit through indoor as shown in the fi gure.
Remove remote controller from Tank Unit, install it in one of the circuit and use it as Room Thermostat.
Install external Room Thermostat (fi eld supply) in another circuit.
Both circuits can set circulation water temperature independently.
Floor heating + Radiator
Outdoor
Connect fl oor heating or radiator to 2 circuits through indoor.
For temperature setting, select circulation water temperature for both circuits.
Both circuits can set circulation water temperature independently.
(Radiator recommended to connect as zone 1 circuit for higher water circulation temperature)
Tank Unit compare between room temperature and setting temperature
on the Remote controller to control HP and circulation pump.
