Install Instructions

– DPM-2 SELECTION SWITCH –

The DPM-2 Outdoor Reset Control is designed to raise or lower the

temperature of the boiler supply water based upon a proportionate

drop or rise in temperature at the outside sensor. The DPM-2 plugs

into a data port on the AZ-CP control with a ribbon cable. If the

DPM-2 selection switch is in the ON position, the AZ-CP will be able

to communicate with the DPM-2. (See the separate DPM-2 Installa-

tion Manual for more information.)
