The XR77CX is a cooling regulator for panel installation, 32 x 74 mm, suitable for normal and low temperature applications.
Four relays are available:
Cooling, defrosting (electrical or hot gas), evaporator fan and an auxiliary input that can be configured for lighting, fault alerts or an auxiliary thermostat.

Thanks to the integrated real time clock (options), it is possible to program defrosting and target value changes (energy-saving mode) for specific times and days.
The available sensor inputs (NTC or PT1000) are as follows:
Room temperature, evaporator temperature and two additional configurable sensors. The third sensor input shares the physical connection with the first digital input so that this input can be used for both digital status messages as well as for analogue measurements.
The integrated RS485 connections allow direct ModBus RTU communication without additional accessories e.g. with a monitoring system or the XWEB range. The regulator can be easily configured using a HotKey parameter storage card. The HotKey connection can also be used for an Xrep remote display.
