CONNECTING POWER SUPPLY AND THERMISTOR CABLE
1. Remove the piping cover
2. Connect the power supply line to the terminal block.
3. Fix the power supply line with the wire holder band.
4. Connect the thermistor cable line to the terminal block.
5. Hold the thermistor cable with the code clip.
6. Attach the piping cover back on the heat pump unit
7. Loosen gland nut on the lower sensor connection port of the tank.
8. Put gland nut over probe and insert probe into bottom sensor location. Ensure it is
pushed in all the way.
9. Tighten gland nut over probe so it is secure and cannot be removed.
Note: If tank sensor does not reach the edge of the tank sensor connection port,
temperature may not be able to be detected, causing an error or continuous operation. If
the 2m sensor cable is not long enough, you will need a 15m sensor cable.
