HM4000C Helio-Matic® Controller with sensors

for 24VAC valve, solar pool heating systems

Basically, it's as simple as setting a thermostat. Simply set the desired water temperature on the Helio-Matic® Electronic Controller. Two precision sensors, one for the pool water, and one simulating the solar collector, signal the controller when climate conditions are right for the water to be heated. If the water temperature is not above the desired setting, the controller opens the Flo-Verter® Valve, sending water through the solar collectors, gathering warmth and returning to the pool. When the desired temperature is reached, the controller automatically closes the operating valve.

Helio-Matic® Electronic Controller:

• Valve output for 12 or 24 VAC valve without any need for adjustment.
• Color-coded wire terminals to match Flo-Verter wire colors.
• Ample interior wiring space without need to access electronics.
• Calibrated control knob for precise maximum temperature.
• Brass material sensor for pool water temperature.
• Aluminium block sensor for collector simulation. Does not need to mounted on the collectors.
• Lightning arc absorbers for sensors.
• Extra UV protection enclosure for longer-lasting like-new appearance.

Unconditionally guaranteed for one year from date of installation.
