The CC1800 Compact Controller makes use of existing sensors!

The out-of-the-box solution from Clarkson Controls.

The CC1800 does everything you need it to, it’s compatible with Drayton, Satchwell, Honeywell, 10K 3A1 and Siemens Sensors.

If you have an obsolete controller then the CC1800 means you don’t need to change your existing sensors.
