Laars Heating Systems HVAC Control Modules: Precision Control for Hydronic Heating
When a boiler or hydronic heating system stops performing as expected, the control module is often at the heart of the diagnosis. Laars Heating Systems has built a decades-long reputation — founded in 1948 and headquartered in Rochester, NH — as a manufacturer of high-efficiency residential and commercial boilers and water heaters. That same engineering rigor carries over into their line of HVAC control modules, which are purpose-built to keep Laars equipment running accurately and safely.
What Laars Control Modules Do
A control module is the electronic brain of a hydronic heating system. It monitors and manages critical functions such as ignition sequencing, temperature regulation, combustion timing, and system safety shutoffs. In a Laars boiler or water heater, the control module coordinates all of these processes to maintain efficient, reliable heat output. Using an incorrect or worn-out module can lead to erratic cycling, inefficient fuel use, or system lockout — making genuine OEM replacements essential for restoring performance.
Key Products in the Laars Control Module Lineup
Laars offers a focused selection of control modules designed as direct-fit replacements for specific boiler and heating appliance models. Notable parts in this category include:
- RXD7207 & RXD7208 — Control modules engineered specifically for Laars NT-series boiler models (including the 600 and 750 MBH configurations), managing the full operational sequence of these high-output units.
- R2087801 — A programmed control module designed for the Laars JX series, one of the brand's most widely installed residential gas-fired boilers.
- RE2344300 — A PCB temperature control module that governs precise thermal regulation within the heating circuit.
- RXN7052 — A CSD-1 programmed control module, built to meet boiler code compliance standards for commercial applications.
Each of these modules is a genuine Laars OEM part, meaning it is designed and programmed to exact factory specifications for the equipment it serves. This matters because Laars products span a wide range — from 50,000 to 5,000,000 BTU/hr — and the control logic for each platform is tailored to its specific burner, heat exchanger, and safety architecture.
Why Choose Genuine Laars Control Modules
Laars' award-winning product line spans residential and commercial boilers, water heaters, controls, tanks, and accessories, and the brand's control modules are engineered as an integrated part of that ecosystem. Installing a genuine Laars control module ensures compatibility with the existing wiring harness, sensor inputs, and safety interlock logic already built into the appliance. For professionals servicing Mini-Therm® JX boilers, FT Series units, Magnatherm systems, or other Laars platforms, using factory-matched modules is the most straightforward path to a reliable, code-compliant repair.
Whether you're a licensed HVAC technician performing a warranty repair or a facilities manager restoring a commercial heating plant, the right Laars control module makes the difference between a callback and a long-term fix.
