Remote Hand-Set with Four Button Control for Schwank Single-Stage Heaters - JP-1236-HS
This is a Hand Set to Control Schwank single-stage heaters. The remote has four On/Off buttons, one for each zone, and each zone can have up to 4 heaters. So you can control up to 4 individual heaters or up to 4 zones with multiple heaters in each zone.
At least one hand set is always required for master programming of receiver or Keypad Transmitter. Schwank recommends ordering two hand sets for each control area so that a back-up hand-set is available if one is misplaced.
OR - order one master hand set and one Keypad Transmitter for each zone.
