If the temperature at the thermostat sensor drops below 5°C, the UPS THERMOSTAT connects the battery with the UPS unit (PG500) and the circulation pump is started. The pump is kept running until the sensor temperature rises above 6°C. This prevents the water circuit of the heat pump from freezing.
Layout principles: • UPS unit (PG500), UPS THERMOSTAT and battery shall be placed close to one another in such a manner that the prepared length (2m) of 12V cables (2 blue cables and 2 red ones) will be sufficient.
. 2. Plug the cable with wall plug into the socket on the UPS (PG500) back side. Wire the live wire from UPS (L-UPS) to the auxiliary relay, contact No. 3. Then wire the neutral lead N-UPS to the pump N clamp (see the wiring diagram).
6 Temperature sensor connection The sensor shall be placed into a heat pump’s heating water sheath. The sheath shall be mounted into the outdoor pipe section, min. 200 mm and no more than 400 mm from the wall. The sheath shall be located downstream the heat pump – see the layout diagram. If the unit cannot be placed in such a way that the supplied 2.5 m cable is enough, the cable may be extended.
8 Operation overview The meaning of indication LEDs: green - circulation pump running yellow - outdoor piping temperature below +5 °C yellow - outdoor piping temperature below +5 °C red - sensor defect Detailed description of all the states: Sensor Mains Temperat.
