Price Silent Guard

Electronic Heating Controls

PSG
The Price Silent Guard Heater Control Module provides efficient operation of duct heaters with a wide range of features to cover all control, safety and troubleshooting concerns. The on-board PCB relays provide quiet and reliable operation to give the end user peace of mind.

Benefits
 

Installation and Maintenance
The design of the PSG greatly reduces installation time and increases convenience: the unit simply snaps in to the duct heater. Wiring connections for every possible configuration are labeled on the board in a straightforward manner. This reduces wiring clutter and space required for assembly. Troubleshooting the unit is even easier. An on-board status LED sequentially blinks out a troubleshooting code which indicates the current status of the board. (For example: three blinks means 3 stages of heating are active, six blinks means auto reset has tripped, etc.) The indicator lights also show the user which individual circuits are currently energized.
Safety
The PSG has undergone rigorous testing and earned ETL approval giving the user comfort in the safe operation of the device. Numerous innovative concepts were incorporated into the design of the circuit board ensuring not only the safety of the building and its occupants, but also the safety and longevity of the fan and heater components.
  • Quiet on-board relays
  • Auto resetting 24VAC fuse
  • On-board air flow switch
  • Status LED to aid troubleshooting
