Whisper Controls is excited to announce the launch of our innovative HL-109 digital pipe thermostat, designed to ensure the safety and efficiency of heating systems.
Backed by our market-leading five-year warranty from the installation date, the HL-109 acts as a fail-safe mechanism to monitor and control the heating system’s temperature, preventing it from exceeding predetermined limits. If there is any anomaly or potential overheating, the HL-109 interrupts the power supply, safeguarding the heating system.
Jon Arntsen, Managing Director of Whisper Controls, said: “At Whisper Controls, we are passionate about delivering straightforward smart living for our customers. The HL-109 reflects that with its user-friendly design and versatility. Thanks to its pump exercise function, it can prevent underfloor heating circulating pumps from seizing during the off-season and particularly protects underfloor heating systems from heat sources that could cause over-temperature failures or high-temperature cycles. This makes it ideal for projects with delicate floor finishes or systems without temperature managing capability in the underfloor heating manifold.”
The HL-109 is the perfect solution for residential and commercial heating systems, offering peace of mind and enhanced protection. For more information, please contact our expert team at 01993 640073.
Key Features of the HL-109:
Low Limit / Frost Protection: The HL-109 provides reliable frost protection by driving a pump, heat demand, or trace heating system to prevent freezing. This ensures that your heating system remains functional even in the coldest conditions.
Pump Protection: To prevent pump seizing, the HL-109 includes a pump exercise function that activates the pump for 5 seconds every 5 days. This feature is particularly useful in low-demand scenarios and significantly extends the pump’s lifespan.
User-Friendly Design: The HL-109 features simple power, up, and down buttons, along with a clear digital display. This allows for quick, accurate setup and easy system checks without additional testing equipment.
At Whisper Controls, we develop and supply the next generation of electrical controls for domestic and multi-residential heating systems. We are a straightforward, innovative controls supplier delivering expert customer support and high-quality smart living.
