The SunStat PRO Programmable Thermostat (500670) is a solid performer for operating your floor heating system since 2007.
This thermostat has built-in Ground Fault Protection for your safety and is fit for use in the US and Canada according to ETL to UL standards. The thermostat senses the floor temperature via a 15-foot Floor Sensor Wire which is included. In most areas, you don't even need another GFCI circuit. Enjoy the sleek design of the backlit display with the programming buttons simply hidden behind a single door.
SunStat PRO is a Dual Voltage thermostat which means it's suitable for 120v or 240v and you don't have to worry about its compatibility with your floor heating system.
Manufactured in-house by SunTouch (not outsourced like many other brands) it was introduced in 2007 (check out the newer models Pro II and VIEW):
- 120v/240v (dual voltage) means you always have the right thermostat regardless of the system voltage on-site.
- Air-sensing Mode with an optional floor temperature override limit.
- Regulator mode takes over if the sensor is damaged or disconnected.
- Master Control Capability for connecting other SunStat 500680 relays to expand your floor heating system.
- 15' long Class 2 Insulated Sensor wire
- 5/1/1 Day Programming settings or manual operation
- 4 preset heating schedules or you can program your own!
- Monitor your usage and check the on time of your SunTouch system through the SunStat Pro. Choose either 12 or 24 (Military time) hour mode for the clock display.
- State of the art SmartStat Technology
- Easy integration with your home automation system through dry contact relay.
- Floor Temp Range of 40 to 99 degrees F, or 5 to 37 C.

- View operation, heat on/off, mode and other details on a large digital display, with LCD for clock and all other functions
- 15 amp capacity lets you control SunTouch 120VAC mats totalling up to 150 SF per control (or up to 300 SF of 240V mats).
- Connection with remote FloorStat sub control relay (MPN: 500680).
- Class A GFCI safety protection is built-in with a test light and button, a 5 milliAmp trip.

- Batteries not required! Save your programming to memory, endlessly.

ThermostatWorks very well and is easy to program.
Love the heat, hate the failure.My SunStat Pro died after almost 4 years. The manual says the error logged is because the GFCI has exceeded its life. Looks like a $40/year service fee to keep my floor running. The warmth is certainly worth the agravation.
Does not keep accurate timeThe clock has substantial drift (several minutes each month) Perhaps not so bad as a thermostat, but not great when you depend on the unit to tell you the time in the morning. Was told by a technician that this was because it is driven off the frequency of my electricity which tests normal and no other clocks in my home have this problem....
The new one was easy to install and has worked like a charm.I bought a new control for my heated floor because the old one failed after only 3 years. But, the new one was easy to install and has worked like a charm.
