V4043 AND V4044 MOTORIZED VALVES
95C-10206—02 6
MANUAL OPERATION
The motorized valve can be opened manually by lifting the
manual opener lever over the stop and pushing slowly and
firmly to the MAN. OPEN position. The stop permits the valve
to be locked in the open position. The valve will return to
automatic position when the valve is energized.
CHECKOUT
1. Raise the setpoint on the zone thermostat above room
temperature to initiate a call for heat.
2. Observe all control devices - the valve should open and
the auxiliary switch should make the circuit to the circu-
lator or other valve at the end of the opening stroke.
3. Lower the setpoint on the zone thermostat below room
temperature.
4. Observe the control devices. The valve should close
and the auxiliary equipment should stop.
SERVICE
This valve should be serviced by a trained, experienced
service technician.
1. If the valve is leaking, check to see if the O-rings need
to be replaced.
2. If the gear train is damaged or the motor is burned out, it
is necessary to replace the entire powerhead assembly.
See INSTALLATION Section.
NOTE: Honeywell zone valves are designed and tested for
silent operation in properly designed and installed
systems. However, water noises may occur as a
result of excessive water velocity or piping noises
may occur in high temperature (over 212° F [100° C])
systems with insufficient water pressure.
NOTE: These hydronic valves are not suitable for use in
open loop systems where there is air exposure.
