Is DualSun compatible with the PANASONIC thermodynamic heater PAW-DHW270C1F?
Yes, the hybrid solar panels DualSun are compatible with the PANASONIC thermodynamic heater PAW-DHW270C1F.
Control of the thermodynamic water heater by the DualSun solar controller
The intelligence of the PANASONIC PAW-DHW270C1F thermodynamic heater allows to optimize its coupling with the solar panels in order to reduce the electrical consumption and ensure the customer comfort at the same time. This could be done by good communication between the solar controller and the thermodynamic heater through an electrical signal avoiding simultaneous heating and giving priority to the free solar energy when it is available.
It is necessary then to connect the relay R2 of the solar controller to the electronic board of the heater according to the figure below.
The solar controller has to be settled following these steps:
- Set the system 1
- Activate the parallel relay option ORPAR = ON
- Parallel Relay: REL = R2
- Reference relay: RELR = R1
- INVER = ON
According to this configuration, the water heater operates only when it receives a signal from the solar controller. When this signal is received, the heat pump starts if there is a heat need and that the heater is in its operating time range. In case of adverse weather conditions, the electrical heater could take over.
Setting up steps of the temperature sensor of the solar controller
|Remove the plug and foam from the housing next to the connections of the internal heat exchanger|
|Push the temperature sensor through the plug (the plug has been drilled for this purpose).|
|Insert the sensor into the chute ensuring that it is well positioned at the bottom of the housing|
|Put the foam back and insert the plug back into the product|
