VC6800, VC6900 SERIES FLOATING CONTROL VALVES

WIRING
One controller and a separate transformer is required to
operate each valve.
Figures 6A and 6B show wiring connections. Port “A”
open
and
closed
denote valve open and closed positions
respectively. On auxiliary switch models, contact makes in
between (NC) terminal 1 (orange wire) and (NO) terminal 4
(gray wire) in mid-range of opening cycle. On Molex™
connector models, valve and auxiliary switch voltage must
be the same to meet approval requirement. When mixing
line voltage and 24 Vac (Safety Extra Low Voltage)
application together, the cable version must be used.

OPERATIONS
WITH SERIES 60 FLOATING CONTROLLER
(refer to Fig. 7)
The series 60 floating controller is an SPDT controller with
a center-off position. On a change in temperature from the
set point, the controller will close the NO or NC contacts,
driving the valve to an intermediate position until a further
change at the controller. The valve is set between the
limits of the controller to satisfy various load
requirements. In the event of a power failure, the valve will
stay at whatever position it was in when the power was
interrupted. When power is restored, the valve will the
valve will respond to the controller demand.

SERVICE
This valve should be serviced by a trained, experienced
service technician.
1.
If the valve is leaking, drain system
OR
isolate valve
from the system. Do not remove body from
plumbing.
2.
Check to see if the cartridge needs to be replaced.
3.
If the motor or other internal parts of the actuator is
damaged, replace the entire actuator assembly.
NOTE:
Resideo hydronic 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.
Piping noises may also occur in high temperature
(over 212 °F [100 °C]) systems with insufficient
water pressure.
IMPORTANT
Do not use boiler additives which are petroleum
based or contain mineral oil, hydrocarbons, or
ethylene glycol acetate. Compounds which can be
used, with minimum 50% water dilution, are
diethylene glycol, ethylene glycol, and propylene
glycol (antifreeze solutions).
CHECKOUT
1.
Raise the set point of the thermostat above room
temperature to initiate a call for heat.
2.
Observe all control devices - 2 way valve should
open. Port A in 3 way valve should open, and port B
should close. The auxiliary switch (if present) should
operate and make at the end of the opening stroke,
activating the auxiliary equipment.
3.
Lower the set point of the zone thermostat below
room temperature.
4.
Observe the control devices. 2 way valve should
close. Port A in 3 way valve should close, and port B
should open. All auxiliary equipment should stop.
USE 105°C (222°F) RATED SUPPLY WIRES ONLY.
