Honeywell T4R Wireless Programmable Thermostat

A programmable wireless thermostat allows you to choose exactly when you want the heating on, and how high or low the temperature should be. The thermostat, thanks to radio frequency communication, can be placed anywhere in the house.
It sends on/off indications to the receiver, placed near the boiler and connected to it with cables.
Set different temperatures at multiple times throughout the day to meet your lifestyle needs.
