Solar SC – Solar Station with Controller

Comprises: solar pump as above and ModvSol 4 controller.  Available in connection sizes 22mm and 1” BSP male.  Supplied with insulation box cover as photograph left.

Description
22mm Solar Station with 6 mtr head circulating pump  | Code:33699 
22mm Solar Station with 8 mtr head circulating pump  | Code:33707 

The unit with 1” (180mm) solar circulating pump, fully assembled and tested, consists of:

Return

  • Flow and temperature combined electronic counter VFS “Vortex Flow Sensor” with draining valve. Flow 2-40 l/min.
  • Solar circulating pump with Molex connector.
  • 3-way ball valve with non return valve 10 mbar (which can be excluded by rotating the handle by 45°) supplied with in-handle thermometer (coded blue, range 0°C-120°C).
  • Security unit 6 bar with manometer ø50 mm 0-10 bar with 3/4” Male connection to the expansion vessel.
  • 3/4” connection with filling valve.

Flow

  • Ball valve with non return valve 10 mbar (which can be excluded by rotating the handle by 45°) supplied with in-handle thermometer (coded red, range 0°C-120°C).
  • Air vent made of brass provided with manual vent valve.
  • TR/S1 silicone temperature sensor in contact with the pipe fitting.

Solar Controller ModvSol 4 prewired including 3 TT/S2 silicone sensors. Power cable with Shuko plug and cable for the circulating pump with Molex connector. Centre distance 125 mm. EPP insulation box (Measurements: 308x434x169). A special back plate fixes the unit to the insulation box and it allows a quick fitting to the wall or to the solar cylinder.

Constant temperature on the flow: 120°C; (short time temperature: 160°C for 20 s). Return: temperature range between 0°C and 100°C. (A short time up to + 120°C, during which the VFS is not recording the temperature, is allowed).

External connections: 22mm compression, 3/4” Male or 1” Male.

The solar controller ModvSol 4, in addition to the same standard functions of the ModvSol 3, has also the function of heatmeter: it measures both the flow and return temperatures with the volume flow calculating the energy provided.

1 switch output to control the speed of the standard circulating pump by electronics to provide and keep the differential temperature “solar collector/storage tank” as uniform as possible.

1 standard output relay to control the circulating pump (230V~) or a valve.
4 inputs for PT1000 temperature sensors.
2 inputs to be used for the counter VFS.

Available circulating pumps:
Wilo Star ST 25/6 (6X), Wilo Star ST 25/7 (7X)
