AD EXPANSION MODULE

AD-1

1. The AD-1 Expansion Module plugs into the ARM-2P, ARM-3P,

ARM-4P, and ARM-6P to provide one additional heating zone.

2. Multiples of AD-1 (single zone) Expansion Modules can be used

to provide up to 15 zones maximum. The 18” connecting cable,

which plugs into the ARM Circulator Zone Relay, is supplied with

the unit. Separate line voltage is required.

AD-4

1. The AD-4 Expansion Module plugs into the ARM-2P, ARM-3P, ARM-

4P, ARM-6P, or AD-1 to provide four additional heating zones.

2. Combinations of AD-1 (single zone) with an AD-4 (4-zone) Expan-

sion Module can be used to provide up to 15 zones maximum. The

18” connecting cable, which plugs into the ARM Circulator Zone Re-

lay, is supplied with the unit. Separate line voltage is required.

NOTE: The AD-4 expansion module does not have an out to

zone module terminal. If additional zones are required a tele-

phone jack tee adapter (Argo Item #J8) can be plugged into the

master control and the output phone cord to additional AD mod-

ules can both be plugged into the telephone jack tee.
