STEP 1 Connect 120 VAC Hot
to terminal L1. Connect 120 VAC
Neutral to terminal L2. Disconnect
means and overload protection as
required (provided by others).
STEP 2 Connect the circulator to
C1 and C2 (C2 is neutral).
STEP 3 Connect wire from 24
VAC Burner Circuit to B1(quick con-
nect). Connect wire from 24 VAC
Burner Circuit common to B2 (fork).
STEP 4 Connect wires from Low
Voltage Thermostat to T and 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 con-
trol 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.
