5.7.4 Continuous temperature control by coldroom sensor
Controller types UR 141 TE, UR 141 NE
Cooling is controlled according to temperature measured on the cold room air sensor. When cold room air
temperature equals the current setpoint, opening duration of the expansion valve is reduced to the time
required to maintain the current state. Cooling can take place in single-zone mode or two-zone operating mode.
In single zone mode, Ry.1 sensors act on Relay 1.
