3 Zone Programmer Operating Instructions

Quick introduction to your R37V2 programmer:
The R37V2 programmer will be used to control three separate zones in your central heating system.
Each zone can be independently operated and programmed to suit your needs. Each zone has up to three daily heating programs called P1, P2 and P3. See Page 13 for instructions on how to adjust the program settings.
On the LCD screen of your programmer you will see three separate sections, one to represent each zone.
Within these sections you can see what mode the zone is currently in.

For `Mode Selection’ please see page 11 for further explanation.
When the zone is ON, you will see the red LED for that zone light up. This indicates that power is being sent from the programmer on this zone.
