The ITR 79.4xx type series has been especially designed for application with heating systems, whereas the ITR 79.8xx type series has been provided for use with floor heating systems. The control devices of these series activate the addressed relays if the temperature falls below the related set temperature value. The related turn on state is signalled by a red LED. The ITR 79.5xx type series, by contrast, has been specifically designed for application with cooling devices and activates the corresponding relays if the temperature passes over the related set temperature value. The turn-on state is signalled by a green LED. The relays are deactivated if a power failure, a sensor breakdown or a sensor short circuit occurs.
