Solar Hot Water Controller ISC-AC2-A3C to suit Oz Roll Sensors not supplied (make sure this is the correct model controller for your system by checking the sensor lead connections).

This controller has three temperature sensors which connect to the controller via short flying leads.

These sensors are:

  • Panel Sensor, usually 15 metres
  • Bottom Tank Sensor, usually 3 metres
  • Mid Tank Sensor (with white band), usually 2 metres

The Panel Sensor will only connect with one of the short flying leads. The Mid Tank Sensor (with white band) connects to the flying lead with the white band. The Bottom Sensor connects to the remaining flying lead.

The Panel Sensor goes to the top of the collector panel, the Mid Tank Sensor goes to a position in the body of the tank and the Bottom Tank Sensor goes to the bottom of the storage tank.

Panel temperature must be sensed as close as possible to the top of the panel either by inserting the sensor into a thermowell in the plumbing fitting or by placing the sensor on the pipework as close as possible to the outlet from the top of the panel.

Mid Tank temperature sensor will require a fitting on the body of the tank so that it can sense the Mid Tank tenperature.

Bottom Tank temperature must be sensed as close as possible to the bottom of the tank, either by inserting the sensor into a thermowell in the bottom of the tank or in the plumbing fitting or by placing the sensor on the pipework as close as possible to the outlet from the bottom of the tank, where water is taken to the panel via the pump.

Put the end of the sensor in direct contact with the temperature to be sensed. On pipeword it can be held in place with tape.

Where possible, insulation should be placed over the end of the sensor and approximately 100mm of cable behind the end of the sensor to ensure that the sensor reaches the temperature it is trying to measure.

If using silicone sealer, only use those with Neutral Cure. Sealers that smell of ascetic acid may cause the sensor leads to become brittle and crack.

Setup and Adjustment:

No setup or adjustment is required for these controllers. Frost protection by circulation is enabled be default. This method of frost protection provides some protection against frost damage, however, freezing can still occur in some circumstances, such as very cold conditions or dead spots in the panel where water does not circulate.
