If a lower temperature is required for the PS19T, turn the temperature adjustment screw
counter-clockwise about 1/8 of a turn (See pages 3 & 4 for adjustment location). Wait 15-20
seconds and check the temperature at the fixture. Repeat this process until the desired
temperature has been achieved.
For PS28T model try to adjust the 2 temperature adjustment screws by about the same
amount so that the lights pulse at the same rate. If you have reduced the temperature
considerably from the 140 F setting, you could now open up the outlet ball valve slightly to achieve
a higher rate of flow.
When the indicator light is on continuously, the unit is emitting full power. When it is pulsing, the
unit is modulating the power to achieve the temperature set by means of the temperature
adjustment screw.
In order to obtain good control at “single lever” mixer type faucets (single spout) the cold water
supply to the faucet should be restricted to give approximately the same flow rate of cold water
to the faucet as the hot water coming from your Powerstar heater. The simplest method of
doing this is by partially closing the cold water valve under the sink.
