WM 100, 150single stage controller for temperature

The WM 100/150 controllers are devices with one point ofintervention only, for wall mounting, they can operate bothfor hot and cold applications. They are provided with a PTCthermostatic probe input and a relay output for loadmanagement. While the WM 100 does not have a display, inthe WM 150 the value of the probe’s reading is viewed on adisplay by two digits. The setpoint is adjustable through agraduated knob. Two leds for the WM 100 and one led forthe WM 150 indicate the state of the relay.
