Honeywell 1 Day 2 Channel Programmer

The Honeywell ST9400A is a 1-day twin channel programmer designed for independent control of heating and hot water in complete systems, enabling maximum energy efficiency. It can be used for combi boilers, heating zones or any application where small electric loads need switching. It can also be set as a mini programmer for older gravity circulation stored hot water systems without an interlocking control valve.

Nest Product Range

Why settle for old technology, when Nest can do it all?

Each Nest product works out how to make your home better. So imagine what they can do when they work together. If Nest Protect detects carbon monoxide, the Nest Thermostat can turn off your boiler, because it's a common source of CO leaks. And when the Nest Protect senses smoke, it can turn on Nest Cam to help find out where it came from.
