KRF-24V-KIT is a 24-Volt RF wireless thermostat platform designed for virtually every type of HVAC system. Designed for applications where you don’t have enough wires, have a broken wire, or if you are adding equipment like an add-on heat pump or a multi-stage system—without the need to run additional wires. The kit includes a 7-day programmable thermostat and a 24V HVAC relay.
ThermaLink wireless RF thermostat is more than just a thermostat. It wirelessly controls any 24V Heat Pump or Conventional System by communicating wirelessly to a 24V relay that is wired to the HVAC unit.
For added flexibility, the system supports optional RF sensors for customized comfort control. It can detect when people are in the room or when a window or door is left open, adjusting the temperature accordingly.
Plus, multiple rooms can be paired to an optional wireless master switch, allowing the entire building to be set back with the push of a button.
