Chronotherm Wireless Programmable Thermostat

The CMS927B1049 Chronotherm is a feature packed wireless 7-Day Programmable Room Thermostat that is typically used to remotely control the temperature of your central heating system.

The CMS927B1049 has been designed to be used as part of a system in conjunction with combi-boilers, oil-burners and gas fired boilers, circulation pumps, thermal actuators, vales zones and electric heating systems.

When being installed the only wiring required is the connection of the relay unit (not supplied) to the device being controlled, such as a boiler. The controller should be placed in an area where the RF (868MHz) communication signal between the controller and relay unit isn’t hampered.

*This is a thermostat unit only, and does not come with the receiver relay unit.

CMS927B1049 Chronotherm Thermostat features:

• Wireless communication between thermostat and relay unit (not supplied)
• Easy to install, powered by 2xAA Alkaline Batteries
• Auto, manual, holiday and off (frost) modes
• EEPROM memory holds user programme even when batteries are changed
• Extra-large, backlit LCD with user friendly display interface
• Can be used to control a 4-zone system
• Up to six time/temperature settings a day
• Synchronised boiler control in multi-zone systems for optimum efficiency
