The temperature sensors used for this controller are PT1000
Please note for standard systems seperate wiring diagrams are not supplied.
Termination cable at sensors, pumps and other devices.
Sensors in solar fields and cylinders:
Temperature sensor for collectors (one per solar field) are located as per the previous
section on sensor location in collectors.
If stainless flexible pipe-work is used, the cable for the sensor is included within the pipe-
work. A termination box will have to be installed close to the collectors if a pre-wired sensor
is used.
Temperature sensor from storage cylinder solar section, (one per cylinder) are located in the
solar section of the vessels.
The destratification pump is located on the solar cylinder.
TEMPERATURE SENSORS:
The standard sensor supplied by Andrews Water Heaters is a glanded PT1000 sensor,
complete with terminal space box for ease of installation.
For glazed flat plate collectors a PT1000 without fitted terminal box is supplied for placing
in the collector sensor position. This can then be wired to a suitable terminal box, for
connection back to the controller.
Mechanical:
The gland on the temperature sensor is adjustable so the immersion length can be altered
to suit location and pipe-work.
The gland has a screwed BSP male connection. This can be utilised with bushes to fit into
any size of connection. (Thes are supplied by Andrews Water Heaters, for cylinder the
connectors).
Electrical:
Please refer to the enclosed manual to ensure correct wiring.
