Programmable Thermostat for HVAC Systems

The VEVOR GM4937 thermostat provides 7-day scheduling for residential heating and cooling equipment. It supports 1 heat and 1 cool stage across underfloor heating, heat pumps, air conditioners and hydronic systems. Homeowners seeking automated comfort control without manual intervention will find the flexible programming suits daily routines.

Battery or Wired Power with Low Draw

The unit operates from two AA batteries or a 24 VAC connection, drawing minimal current in either mode. A backlit HTN display remains legible in low light while an automatic sleep mode conserves power when idle. Normal operation produces no audible noise, making it suitable for bedrooms and quiet living areas.

Mounting Hardware and Manual Included

The package supplies two flat-head screws, two self-tapping screws and two expansion anchors for surface or junction-box installation. A printed user manual guides wiring, sensor placement and schedule setup. No additional software, apps or accessories are bundled, so configuration is completed directly on the device.

Questions about this item

How do I wire the thermostat for 24 V power and which step is often missed?

Connect the 24 V AC wires to the terminals, insert the two 3 V dry batteries as backup, then mount the unit using the supplied expansion anchors and both flat-head and self-tapping screws; the step most people skip is fitting the batteries so the schedule survives a power cut.

What will need replacement during the life of the GM4937?

The two 3 V dry batteries that back up the 7-day program and clock will need periodic replacement; the LCD backlight and touch buttons are built into the sealed HTN display module and are not user-serviceable.

What is the first limit reached when the thermostat runs continuously in a hot environment?

The upper temperature limit of the control range is 99 °F (37 °C); beyond this the thermostat cannot call for cooling or display a higher set-point.
