The CCTHV-407 thermostat from Cristal Controls is a thermostat operating in stand-alone mode or with an RS-485 communication port supporting the BACnet MS / TP protocol.

In stand-alone mode, the thermostat operates like a standard electronic thermostat (pulsation of a 24 VAC output depending on the ambient temperature). The very complete algorithm of the CCTHV-407 can be adjusted by several configurations, making it a thermostat that harmonizes with all kinds of situations.

Dans sa version complète il est doté de 7 sorties et 4 entrées. (2 heat, 2 cool, 1 fan, 1 aux, Occupation et plus)

It is perfect for operators of multi-residential and commercial buildings, it allows advanced management by the owner, in an automated way.

Via a BACnet system, it can easily allow remote management of premises occupancy, temperature monitoring and configuration.

Only Thermostat with a variable "PowerLimit" facilitating any load shedding system to limit the power according to the monitoring of the building consumption, without affecting occupant comfort.

In needy settings, it can serve as a point for a call-on-call system. (Zipper)

A perfect ally for energy efficiency and automatic regulation of your building.

Maintain and continuously increase the performance of your building with the CCTHV-407 thermostat.
