Honeywell TG510A1001/U – Frequently Asked Questions

1) Will the Honeywell TG510A1001 thermostat guard fit a Honeywell T87 round thermostat?
Yes. The TG510A1001/U small universal guard is specified for use with the T87 and other thermostats of similar size. The inside opening measures 4-7/16 in. (113 mm) high by 113 mm wide, so measure your thermostat against that before ordering.
2) How tamper-resistant is the Honeywell TG510A1001 guard for a school or apartment common area?
It uses a tamper-resistant lock where the key cannot be pulled out unless the guard is in the locked position, so a maintenance tech can't walk away leaving it open. Double-wall construction adds a further measure of tamper resistance. Good fit for corridors, classrooms and lobbies where residents keep adjusting the setpoint.
3) How much wall space do I need for the Honeywell TG510A1001 thermostat guard?
Outside dimensions are 5-7/8 in. high by 5-7/8 in. wide with a 2-1/2 in. depth (149 x 149 x 64 mm). That depth is what usually catches people out in a corridor or behind a door swing, so check clearance before mounting.
4) Can a thermostat guard be mounted over a junction box, or only flat on drywall?
The TG510A1001/U mounts on a wall or directly on an exposed junction box, and it can go on vertically or horizontally. That covers both new construction and retrofitting a guard onto a thermostat already in service.
5) Will a locked thermostat guard throw off the temperature reading?
The guard base is vented to let air circulate across the thermostat, which is what keeps the reading accurate once the cover is closed. The cover itself is clear acrylic on the ring base, so tenants and staff can still read the setting without unlocking it.
6) What materials is the Honeywell small thermostat guard made from?
Two pieces, two materials: the ring base is clear acrylic so the thermostat stays visible, and the wallplate behind it is opaque polystyrene.
