EXPANDED DIGITAL MANAGER
10 & 15 ZONE MANAGER INSTALLATION INSTRUCTIONS
1. Remove cover from junction box.
Use a free knockout on the top of the junction box to mount a second or third transformer, wire black lead to
“XFMR” and white lead to “NEUTRAL” on relay board in box. (Use sections marked “120 VOLTS” only.) A
second junction box is not needed for the expanded Digital Manager. Wire additional transformer(s) in parallel
with first transformer. To wire in parallel, wire terminal “A” on one transformer to “A” on the other. Repeat with
other low voltage terminal “B”. Verify 24VAC output from all transformers BEFORE reconnecting the Manager.
2. Mount long panel on top of box cover with long screws provided in lower 4 holes with spacers down.
3. Mount expanded Digital Manager to cover plate over 4 long screws and 2 wide bolts (top 2 holes).
4. Wire the bottom half of expanded manager as 5 zone Digital Manager. For top half, attach one thermostat lead
to a zone and the other to A1 on lower half of manager. Attach one lead from zone valve or relay to
corresponding zone output and the other lead to 24VAC on lower half.
5. Option switches control energy recovery for extra zone outputs (see Digital Manager Option Switch Settings).
NOTICE:
When operating without an expanded manager, use a service card for the bottom half and jumper upper
zones from T
(x)
to Z
(x).
