Honeywell offers the RM7896D1027, a microprocessor-based primary control unit designed for on-off operation. Weighing in at just 2 lbs, this device is rated for 120 VAC and functions optimally at input frequencies of 50 or 60 Hz. Its robust design allows it to operate in extreme temperatures, from a minimum of -40°C to a maximum of +60°C, making it suitable for various applications.
As an essential component of heating systems, the control features an interrupted pilot type, with a pilot flame establishing period customizable to either 4 or 10 seconds. The postpurge timing is fixed at 60 seconds, ensuring safe and efficient operation after shut-off. This unit can handle a maximum load of 2000 VA and has a power dissipation cap of 10 W. Additionally, it requires fusing of 15A fast blow, Type SC or equivalent, which reinforces its reliability.
Installation is straightforward with a plug-in module that connects to the Q7800A or Q7800B wiring subbase. In terms of environmental factors, this control can function effectively in relative humidity levels up to 85% (non-condensing). The main flame establishing period is set at 10 seconds, providing a balance between quick ignition and thorough safety checks.
