brilliant Radio Frequency Programmable Room ThermoStat, the Grasslin STTR/F Towerstat RF

  2010-06-23         admin         Product News » Heating News
We have recently updated this item on our website - the Radio Frequency Programmable Room ThermoStat RSRF, manufactured by Grasslin (their code is STTR/F Towerstat RF). This thermostat can replace most common residential thermostats and is designed to be used with electric, gas or oil heating control systems or cooling systems. Unlike conventional thermostat devices, this control is a new type of thermostat which separates the functions into two units:
  1. The Receiver serves for wiring connections and heat/cool on/off control
  2. The Transmitter serves as the user interface and for temperature sensing / control.
The two units are linked by radio frequency (RF). The advantage is that the user can keep the Transmitter nearby and can read / control the temperature of the living area in immediate use. The Towerstat RF operates on 434 MHz. This is a common frequency used for various household products and as such may on occasion experience crosstalk from other RF operated devices. Read more below about the features of this RF thermostat, the receiver and the transmitter, and where to find out more details about this fitting.
