Description for Tekmar 054

The Room Temperature Unit (RTU) 054 consists of a temperature sensor and an adjustable dial which is used to set the desired indoor temperature. The RTU 054 dial has a temperature range from 40 to 100°F (4 to 38°C). In cases where a restricted temperature range is required, the dial rotation can be limited using limit pins supplied with the RTU. A 10K temperature sensor (eg. 071, 072, etc.) can be mounted remotely from the RTU. This RTU does not work with older tekmar controls.

Optional Devices: tekmar type #: 071, 072, 073, 076, 077, 078, 079

Comments about Tekmar Room Temperature Unit (RTU) 054:

Needed to replace some old Tekmar RTU 054 units and PexSupply filled my order in a timely fashion and everything arrived in fine condition. The old RTUs would occasionally call for heat and then keep the furnace running well beyond the setpoint. The replacement units fixed the problem.

Perfect replacement for malfunctioning unit. Original RTU measured correct resistance but still ran heat way beyond set point. Replacement restored function of Tekmar 370 to normal.
