Hydrolevel 3200 - Manual (Page 3)

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.

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).
