Most commercial thermostats go up to 90°F or 94°F maximum. I was able to find one thermostat - the Jackson Systems Model T-32-P which can be programmed up to 122°F heating set-point.
It actually seems to be a very versatile device, with a ton of flexibility for many different systems:
- Up to 3H/2C conventional and heat pump systems
- 7 day programmable
- Large backlit display
- Auto or manual changeover
- Keypad and/or setpoint lockout
- Smart fan logic for commercial control
- Adaptive recovery
- Optional indoor sensor (T-32-S1 or TS-32-S2) or outdoor sensor (T-32-OTS)
- Outdoor temperature display with optional outdoor sensor (T-32-OTS)
- Available with integrated Modbus communications (Version 2.20)
