Honeywell T3C110AEU

Honeywell T3, Programmable thermostat, 7-day program, T3C110AEU
This is a brand new type of thermostat from Honeywell, replacing the older CM707 model.
It is a wired version of the Honeywell T3 thermostat.

The T3 series thermostats are compatible with a wide range of boilers and systems including 24-230V on/off, such as gas and oil boilers, combi boilers and heat pumps. The OpenTherm control must be purchased separately. T3 thermostats cannot control electric heating.

For the user, the T3 range offers features that ensure that users of the controls can be restricted from unwanted use of the controls. The thermostat can be locked to prevent unnecessary interactions, and upper and lower setpoint limits ensure that extreme temperatures cannot be set.

The T3 has been designed with an intuitive user interface.
This makes it easy to program and use. Use and target setpoints are easily visible and interaction with the thermostat is via a small number of touch buttons.

Other benefits for property owners include automatic daylight saving and standard time change, battery low indicators, service timers, and safe mode. T3 thermostats allow for 5/2 or 7-day programming with 4 time intervals per day.

The T3 provides a variety of energy efficiency measures.
A full suite of optimization functions (Optimum Start, Stop and Delayed Start) plus adaptive "fuzzy logic" protocols provide full control of the boiler. These functions detect that the desired temperature is reached at the desired time without the user having to set the heating start in advance.

Installing thermostats in either wired or wireless versions is easy and this will be appreciated not only by the technicians maintaining your equipment in working order.

The T3 is the ideal choice for homes that require a high level of automatic control and demand significant energy efficiency for a wide range of boilers and systems.

Users can temporarily override the set temperature display and the screen will show the current date and time.

Large screen with easy-to-recognise icons and 5 control buttons
