UNI TEMP is an constant temperature controller with VF sensor and
adjustable temperature setting. It is designed for operating 3-way mixing valves and 2-way control valves. FIRŠT UNI TEMP controllers allow easy installation.

Actuators are available in 230V AC 50 Hz with adapter and are supplied with a 1.7m attached connection cable. Actuator can be manually operated with handle and button on the cover.

UNITEMP actuators are recommended for: maintaining a constant
temperature in boiler heating circuit (protection against condensation), use in under floor heating applications, industrial processes, heat accumulators and in domestic hot water systems or swimming pools (individual systems, SPA, public swimming pools). Actuators UNI TEMP are recommended for mixing applications with: FMV 130/130C, FMV H-151/151C, FMV 140/140C, FMV G-131, FMV 140. And for 2-way valves: FBV 200C-M and FBV 690 valves.
