Fenwal 35-705501-001 Control Refrigerant This HVAC control board integrates

This HVAC control board integrates a sophisticated fan timer control circuit that manages the post-purge and pre-purge cycles of the blower motor to optimize heat exchanger thermal discharge

This kit is engineered for seamless integration with Belimo AF/NF series actuators

System Efficiency: Manages precise blower motor speeds and heating element sequencing to reduce operational wear

Technicians can easily adjust the switching points across the actuator's full range of rotation (0-100%) using a simple dial

always measure the immersion length and check the kW rating on the flange of the old element to ensure a match

Fenwal 35-705501-001 Control Refrigerant This HVAC control board integratesWhen you need a reliable direct spark ignition control for 120 VAC gas fired systems, the Fenwal 35 705501 001 stands as a professional grade solution. This microprocessor based module is engineered to manage the gas valve and spark ignition for natural, LP, and manufactured gases in applications up to 400,000 BTU. Integrated with a 4 second trial for ignition (TFI) and a single try ignition sequence, it provides rapid startup without a pre purge
