At North Coast Power & Water, we stock a full range of Detlasol BS4 / Resol controller sensor cables to suit all Resol Controllers (including the Round Apricus Controller with no display)
The standard roof sensors are 20mtrs.. You cannot use a "tank" sensor as a "roof" sensor as the temperature rating of the roof sensor is much higher (e.g. the Apricus collectors can reach in excess of 150°C+ in Summer time and during stagnation!
How do I know if I need a new sensor for my Apricus solastat controller?
The Deltasol / Resol controller will show a fault that says 888.8 or -888.8 which happens when a sensor fails, or the two wires are cut for some reason (e.g. bird, vandalism, rodent) Take note of the reading next to the fault
- COL = Collector
- TST = Tank Storage Temperature
- S3 = Top Tank Sensor (Sensor 3)
This will give you an indication of the sensor that has failed or is damaged.
