Danfoss Randall introduces RF programmable room thermostat
Published: May 2009
Danfoss Randall’s TP4000 RF wireless programmable room thermostat can be used with combination boilers to provide the same control schedule of room temperature each day. These wall-mounted units have all the features of the popular TP4000 wired controlled. They have a range of up to 30 m to a hard-wired RX1 receiver (illustrated) located near the boiler or other appropriate control component. They have a large LCD panel and are battery operated. When replacing existing thermostats, only 2-wire connection is required. Up to six changes of room temperature can be set each day, and regular settings can be over-ridden on or off until the next programmed change. There is an adjustable frost-protection feature.
