The TH RTU sensor reads analogue Temperature and Humidity. This sensor can be used by the Dream 2 control systems but in this case remotely from the controller. There is options to connect on a Dream 2-wire cable system or Dream Radio system. The TH RTU can be installed as a standalone sensor or be used at a location to also activate solenoids. The sensor can be used activating frost protection and cooling programs at the right time before the temperature drops or raises to a critical point. This information is displayed as an instant reading on the controller or historical graph, remotely on either PC, smart phone or tablet phone or tablet.
