SUNRASERG 220V CONTROLLER KIT FOR SPLIT SOLAR HOT WATER SYSTEM, 3 SENSORS

SUNRASERG 220V CONTROLLER KIT FOR SPLIT SOLAR HOT WATER SYSTEM, 3 SENSORS

KSh7,200.00

SUNRASERG 220V CONTROLLER KIT is a solar controller for solar hot water systems. It is a standard differential controller used to turn a solar hot water system on and off via pump controls.

This solar controller can be used to monitor and operate the solar thermal systems via the relay controls used to operate the solar pump and heater. The pump is activated when one of the three temperature sensors shows there is heat to be collected in the solar array. This solar controller allows for maintenance free operation of your solar thermal system. This solar controller is also equipped with an easy to read display.

Sunraserg solar controller is the ideal choice for large and small systems alike.

Sunraserg solar controller is the ideal choice for large and small systems alike.

Kit includes:

  • Inputs: 1 x Pt1000 sensor  (≤ 500 Cel. degree)  for solar  collector  (silicon  cable≤280Cel. degree),
  • 2  x  NTC10K,  B3950  sensor  (≤  135Cel. degree)  for  tank,  (PVC  cable  ≤105Cel. degree),
  • Outputs:  3 relays, for circulation pumps or 3-way electromagnetic valve, 1  relay  for  electrical  heater
  • 1 x controller
  • 1 x display unit
  • 1 x UK plug

Operation overview:

The solar circuit pump (R1) is switched on as soon as the switch-on temperature difference (△T on) between the collector array (T1) and the storage tank (T2) is reached.

If the temperature difference between the collector array (T1) and storage tank (T2) drops below the switch-off temperature difference (△T off), , or the temperature of storage tank (T3) reaches the preset maximum storage temperature, then the solar circuit pump (R1) is switched off.

Back-up heating by auxiliary boiler: within the preset time section of back-up heating, if the temperature T3 is below the switch-on temperature, then the circulation pump ( H1) of back-up heating is triggered, when T3 is heated to the switch-off temperature, circulation pump H1 of back-up heating is ceased.
