WIRING

STEP 1

Connect 120 VAC Hot to

terminal L1. Connect 120 VAC Neutral

to terminal L2. Disconnect means and

overload protection as required (pro-

vided by others).

STEP 3

Connect the circulator

to C1-C2. (C2 is neutral.)

STEP 2

Connect the burner

circuit to B1-B2. (B2 is neutral.)

WARNING

Electrical shock hazard. To prevent electrical shock, death or equipment damage, disconnect power supply before
installing or servicing this control.

3

STEP 4

Connect the thermostat

to T-TV.

STEP 5

If the boiler is equipped

with a plug-in style vent damper, unplug

the factory installed jumper from the

receptacle on the circuit board and

replace it with the vent damper plug.

NOTE: Once a vent damper plug is

connected to the HydroStat, the control

is permanently altered and will no

longer function when the vent damper

plug is disconnected.

ZONE VALVE WIRING

IMPORTANT: Use a separate transformer to

power zone valves. Connecting zone valves to

Z-TV may overload the HydroStat and cause a

lock-out condition (see

Troubleshooting

on page 6

for more information). The total load, including the

burner circuit, vent damper, and Z-TV connections

must not exceed 1.2 amps (30 VA). Connect zone

valve end-switch to T-TV as shown below.

STEP 6 For Systems with Indirect Water Heaters

When installing with an indirect water heater, the signal from the indirect must be

separated from the heating zone signals and wired to I1 and I2 as shown above.

Calls to I1 and I2 will bypass the Thermal Targeting feature and allow the boiler to

fire to the high limit setting to heat the indirect tank.

NOTE: If you choose not to separate the indirect signal from the heating zones,

the Economy Feature should the turned OFF to insure that the boiler supplies ade-

quate temperature to heat the indirect tank (see page 4).
