Item Description
DIFFERENTIAL ELECTRONIC THERMOSTAT SOLAR WATER HEATING PUMP CONTROLLER 12V 10A
Technical data:
1. Voltage - 220VAC
2. Temperature range: from 0 C to 90 C
3. Differential range form - 0.3 to 50C - set with trimmer.
4. Direct Output : 7A/250V AC
5. Sensors - NTC 10K not waterproof.
Plate dimensions ? 35x49 mm.
Length of wires on probes - 25 cm,

Make good insulation of wires when probes are
extended.
Method of work - Whenever the Probe 2
is measured to be hotter than the Probe 1 , the output NO contact of the
relay close and led come on. The output remains on until the measured
temperature difference between the two sensors has fallen depending of the set
differential by the trimmer.
Setting differential temperature:
The trimmer need to be at average position initially. Rotate it at left
and right precisely until led go off.
In this way thermostat is set at the lowest differential temperature and
is ready for work.
When you rotate it counterclockwise - increase differential temperature.
Please note that trimmer is not so precise and small rotating make big change
of the temperature between two sensors.
For example - Probe 1 can be located at the output pipe of hot water
boiler and Probe 2 - to Output pipe of the solar panel. The output can drive 220V up to 10A water pump.
In this way - when solar panel is hotter than boiler - the pump will come
on.
When Differential temperature of the two probe come equal to the set by
trimmer - the relay will be deactivated.
