Jackson Systems Temp-LimiterT Model TL-73H.
A great product for landlords and property managers! The Temp-LimiterT is wired between an existing room thermostat and the furnace, and prevents space temperatures from exceeding 73 degrees!
Now is the time to take action against increased energy costs caused by tenants setting heating temperatures higher than necessary.
Temp-LimiterT is the low cost, easy to install, temperature limiter that prevents the heating temperature from exceeding a fixed limit, even if the tenant sets the thermostat higher. Model TL-73H limits heating at 73° (+/- 2°). Includes 1 year limited warranty.
Warning; Temp limiter should not be used with Zone Valves (like Taco) that require over 1 amp or power stealing thermostats (such as Honeywell T8775A).
Dimensions: 4.5" H x 2.75" W x 1" D.
The Temp-LimiterT interrupts the connection between the furnace and the "W" terminal on the room thermostat
