Honeywell Compact Corona Series Bedienungsanleitung
V5442N Compact
4-way Rotary Mixing Valves
APPLICATION
The “Corona” series of Compact Rotary valves and
Actuators provide integrated mixing of boiler supply, boiler
return, loop supply, and loop return water in hydronic
heating systems. The V5442 is very effective for low
temperature loops such as radiant floor heating.
The V5442 4-way valve can mix both loop supply water
and boiler return water simultaneously to control loop supply
temperature and boiler shock or flue gas condensation
protection. They may be plumbed in either a direct mixing
or injection configuration.
The effective Cv of the valves is increased when piped in
an injection configuration.

The valve must be oriented correctly towards the boiler
supply water in order to work correctly. Boiler supply water may
enter vertically from below, or horizontally from the left, or right of
the valve. Mixed loop supply exits the valve horizontally (left or
right) with bottom boiler supply, or from the top with left-handed
or right-handed boiler supply. The position indication scale must
not point to the floor.

D. If using the valve manually, clip the stop pin from the molding
sprue on the handle and insert the pin in the hole, according to
Fig.3. Assemble the handle onto the valve.
E. For other valve orientations, use the manual handle to align the
position indicator on the valve’s square drive socket with the
mixed output port. The mixed output will be either be 90°
counterclockwise or clockwise relative to the boiler supply
input port. Insert the stop pin into the appropriate hole on the
handle and assemble the handle to the valve body.

.
SETTINGS
The indicator scale on the V5442 ranges from 1 to 9,
where 1 (minimum) corresponds to no flow from boiler to
loop and full return of boiler supply to boiler return. This
scale is approximately proportional to radiation heat out-
put, and inversely proportional to boiler return water tem-
perature, but is not calibrated and intended for reference
only.
OPERATION
The rotary control plug of the V5442 diverts boiler supply
water to both the loop supply and boiler return. At the
same time, the control plug also diverts loop return water
to the boiler return and back to the loop supply. When the
loop does not use much boiler water, most of it is returned
to the boiler. The loop supply water temperature is the
result of mixing boiler supply and loop return water, and
boiler return water temperature is the result of mixing loop
return water with boiler supply water.
The control plug has a modified equal percentage mixing
characteristic on the mixed loop output to give linear
heat output in the space. The plug uses a linear mixing
characteristic on the mixed boiler return to give linear
temperature control of boiler return water.
The V5442 may be used to control space temperature for
comfort, boiler return water temperature to prevent boiler
shock and condensation, or both simultaneously, depend-
ing on the sophistication of the control system.
In low temperature systems such as radiant floor heating,
the V5442 may be used for mixing in an injection configura-
tion (See Fig. 8). In these configurations, the V5442 has an
effective Cv of a much larger valve.

CHECKOUT AND TEST
Checkout
1. Turn on loop (and main) circulators. Set the boiler
Aquastat control to its operating setpoint at design
conditions.
2. Rotate valve handle to 9. Verify that all boiler supply
water is being sent to the loop, that is, that the loop sup-
ply pipe is the same temperature as the boiler supply,
and the boiler return pipe is the same temperature as the
loop return pipe.
3. Rotate valve handle to 1. Verify that all boiler supply
water is being sent to the boiler return, that is, that the
loop supply pipe is the same temperature as the loop
return pipe, and the boiler return pipe is the same tem-
perature as the boiler supply pipe.
4. Rotate the handle to set desired mixed loop tempera-
ture. Verify that the boiler return water temperature
meets the boiler manufacturer’s or industry recommen-
dations. Make
a prominent note of the setting for future reference.
Note: If the boiler is fitted with a reset control such as the
AQ475 Aquatrol Outdoor Temperature Compensator, loop
temperature will vary proportionately with the boiler supply
temperature.

SERVICING
The V5442 is designed to give years of trouble-free operation,
provided it is used in an oxygen-depleted hydronic heating
system. The V5442 may be used in a combo heating system
only with heat exchangers between the potable and hydronic
heating systems.
Since the V5442 is a gate-type valve, we recommend that
the hydronic system be flushed before putting the valve into
operation to minimize potential damage to the seals by
debris in the system. We also recommend adding Y-strainers
and a 10% side-stream filter to the system after flushing to
capture debris that may be added in future through the boiler
feed water valve.
In automatic control systems where the V5442 has been
motorized with an M6063 actuator, the V5442 should be
operated every 3 days or so during the off season to ensure
the valve does not seize up.
If the valve stem starts to leak, replace the O-ring as shown
in Fig.9.
