DESCRIPTION

The ZoneTrol is a ready-to-install multiple-zone controller for

circulator pumps in hydronic systems. The ZoneTrol con-

trollers feature switchable priority, powerful transformer, auto-

matic resetable fuse and a built-in 30 minute timer on priority

circuit. The units are operated by two-wire 24-volt thermo-

stats and requires connection to a 120 V, 60 Hz source voltage.

BEFORE STARTING THE JOB

Please read instructions completely before starting work

The applications for the ZoneTrol zone pump controllers are

too numerous to show all the various illustrations for the dif-

ferent models. The ZT-4 (four zone) and ZT-2 (two zone) pump

controller will be illustrated in this manual for installation and

application purposes. The other multiple zone pump con-

trollers are installed in a similar matter. The circuit diagrams

indicate the proper terminals for wiring the ZoneTrol for most

applications.

All work must be performed by qualified personnel in

accordance with all applicable codes and ordinances.

Electrical connections must be made using copper wire

only.
