An optional occupancy sensor in line allows the WINDOW WATCHER to set the thermostat back when a room is unoccupied, potentially saving you even more. Motels can use contacts that are key card or key activated to begin room heating when the room is occupied, keep the heat to a minimum when unoccupied.

ThermaLink: A Multi-System Thermostat That Runs Itself. ThermaLink adapts to a building’s changing climate demands, offering full control of a heat pump’s heating and cooling functions while supporting reliable backup from existing line-voltage electric heaters. It allows buildings with existing electric heaters to upgrade to a heat pump system, retaining the original heaters as backup. It meets State Energy Code requirements by using automatic controls that only activate emergency electric heat if the heat pump cannot maintain the desired temperature. The standard kit includes a 7-day programmable thermostat, a 120/240V 20A electric heat relay, and a 24V HVAC relay. Optional wireless RF sensors can detect when someone is in the room or if a door or window is left open and adjust the temperature automatically. An outdoor sensor can be added to limit electric heat use when the heat pump can meet demand, and enable it when outdoor temperatures fall below the heat pump’s effective range. Plus, multiple rooms can connect to a wireless master switch, letting you adjust the whole building with one button.

The HW-FS (hot water) Series with Fan Only Switch is intended for use as a 2 circuit thermostat controlling a circuit pump and fan on a hydronic coil heating system, though it could be used when needing a 2 circuit control with 1 minute delay on the second circuit. This control solves the historic problem of using a standard 22 Amp bi-metal heating thermostat on a hydronic system which require high Amp loads to be accurate. Without a load they will not shut off properly, continuing to circulate hot water when not needed. This control positively controls both circuits creating energy savings and superior comfort control, while providing excellent hydronic control. The HW-FS includes a Fan Only switch, allowing for fan only cooling operation in the summer months.

This is really a good more basic thermostat. We have had the same ones, but low voltage versions, for 15 years, but I needed one for a new 240V heater, so I got the same style. It works great and I love that it mostly matches the others (except the lighting color). The back lighting color changes with the temperature, which a lot of people will probably like. I don't mind it, but I would probably have preferred that I could set it at whatever color I like, but it's not something I would deduct stars for. Overall, it's a nice looking unit that provides exactly what we need and performs it's job well. Update: Thermostat reads about 2 degrees lower than true temperature, but otherwise functions well. I just have to set it at 66 instead of 68 so I don't bake. Not a big deal.. Charles. US. Sun Dec 24 2023
