Pool Heating Control Unit SUNREG[Wi]
An autonomous solar water heating system for pools or hot tubs with internet connectivity maximizes heat gains from sunlight, prevents overheating during hot days, automatically starts with daylight, and after sunset can switch circuits and run filtration for a preset duration without any user intervention throughout the summer. The manual mode then allows you full control over valves and the pump.
Popis
SUNREG[Wi] is a microprocessor-controlled unit that automatically manages regulation and maximizes the heat harvested from solar panels to reach the desired pool or hot tub water temperature without the need for user intervention. You no longer have to monitor sunlight conditions or manually turn the heating on and off every day.
The unit supports internet connectivity, and thanks to the mobile app, you can keep everything under control. The firmware is updated online.
The unit features inputs for temperature sensors, outputs for a motorized heating valve, and a motorized filtration valve. It includes a 230V power cable and an output socket for the pump. The sockets are equipped with waterproof covers that protect connectors from moisture when plugs are not connected.
A waterproof membrane keypad with three buttons for setting the control mode and operating the device is located on the transparent lid of the waterproof enclosure.
The valve outputs are designed for connecting 12V 500mA motorized heads with a single switch for valve operation.
The valve uses an internal connection scheme 303, where the motor is powered by 12V. When the control wire is supplied with 12V, the valve opens. It switches off automatically in the end positions.

The control unit is equipped with Wi-Fi/Bluetooth communication, and its status can be monitored and configured via the mobile app. SUNREG-Wi fully replaces the previous model SUNREG-23, which will be discontinued.
Inputs and Outputs
- Input voltage: 230V
- Output socket 230V max 10A switched via relay for filtration/circulation motor
- SP13 3-pin input connector for temperature sensors
- SP13 3-pin output connector for heating valve
- SP13 3-pin output connector for filtration bypass valve
Package Contents
- SUNREG23 control unit
- External temperature sensors with 2m cables and SP13-3 connectors
- Quick setup and connection guide in CZ/EN/FR/IT/PL/HU
The control unit has IP64 protection (dustproof and protected against water splashing from any direction) and can therefore be used outdoors. However, we recommend placing it in a location protected from direct weather exposure due to possible condensation caused by temperature changes.
The factory configuration is set for 12V/500mA motorized valves with wiring scheme 303, also available in our offer. The valve output provides DC ±12V and a switched +12V.
