Painter Solar Water Heater Temperature Controller Thermostat with Sensor Digital Display: Dual sensors with independent control
This solar water heater temperature controller is for homeowners who want to optimize their solar hot water system for energy savings and reliability. While many focus on basic temperature control, this device acts as a smart manager for your entire setup, preventing issues like overheating or freezing that can damage components.
You get precise control with a 0.1-degree resolution, allowing you to fine-tune settings for maximum efficiency. The dual sensors monitor both the collector and tank independently, so you can set differential modes to activate the pump only when it's beneficial. For example, the freeze protection automatically kicks in at 3°C to safeguard your pipes during cold snaps. The large LCD display shows real-time temperatures with clear zone indicators, and customizable alarms alert you if temperatures exceed safe limits. With overheat protection and a 10 Amp relay capacity, it handles demanding conditions while keeping power consumption under 3W. Installation is straightforward thanks to the panel-mounted design and included wiring diagram.
