4.10Water Temperature Sensing

•Phase 1-4uses a thermistor for sensing the water temperature. It is located within the Motor Controller. User can adjust the warm temperature by going into the Option Adjustment Mode.

•Phase 5 GW uses a thermistor for sensing the water temperature. It is located in the mixing chamber. This is a replaceable item and has a resistance of 10k ohms @ 25oC. 12.5k ohms @ 20oC.

•Phase 5 MW is not fitted with a thermistor. Cold water temperature is the same as the cold water supply. Hot water temperature is the same as the hot water supply. The warm water temperature is achieved by pulsing hot or cold valves. User can adjust the warm temperature by going into the Option Adjustment Mode.

•Phase 5 LW & AW is not fitted with a thermistor. Cold water temperature is the same as the cold water supply. Hot water temperature is the same as the hot water supply. The warm water temperature is achieved by turning both hot or cold valves on. User can adjust the warm temperature by adjusting flow of taps.

Fault code 11 will result if the resistance of the Thermistor is outside the normal limits, the fault is probably due to an open circuit in the Sensor line. For more information on water temperature adjustment see section 7.1. If the required temperature cannot be attained a Smartdrive will give a user warning, see section 10.0 NB: Poor temperature accuracy will result if a digital water valve is used in place of a proportional valve or if the water valves have no flow control washers when used with high flow.
