Caution:
Loose cables can cause
overheating of terminals
or incorrect operation
of the unit. Fire hazards
may also exist. Therefore,
make sure all cables are
connected tightly.
Operation
Allows generating heat, if conditions are
favourable, by modulating the valves in
accordance with the impulse probe, in an
attempt to reach a maximum temperature
of 50° C.
Up to four hot water coil stages can be con-
trolled. These start as indicated by the call
manager and will be limited by the impulse
temperature (30, 40, 45 and 50°C).
Favourable conditions are understood as
water temperature being over 30° C 5'
after the valve opens. Once the system is
in operation, constantly check conditions
remain favourable.
Should unfavourable conditions be detected,
and there is a call, 20' will be timed and
conditions will be checked again.
If opening is over 20%, water pump relay
K1 is activated. If opening is below 5%, this
relay is deactivated.
If conditions are favourable, the yellow LED
(V2) will be on permanently. If not, it will
be off.
When water temperature is below 3° C, the
pump is activated and the valve opens 100%
�
to protect the hot water coil against the risk
of freezing, and this condition is maintained
� ������
until the water temperature rises above 6°C.
This protection is in operation as long as
������
�
the fan is off, even if the machine is off or in
�
�
lockout. As long as the antifreeze protection
is in operation, the yellow LED (V2) goes on
and off. As long as the hot water coil heating
is in operation, the indoor fan is also on.
There is a 15°C air impulse minimum tem-
perature protection when this accessory is
installed. This avoids the discomfort that can
arise when there is a very high renovation
percentage with low outdoor temperatures
and the fan is in continuous operation. If
there is a call for cool, the water coil valve
closes.
The valve actuator is powered by 24 VAC
between terminals 1 and 2. The control sig-
nal is from 0 to 10 VAC between terminals
3 and 4. With 0 VAC the valve is closed
���
(by-pass) and with 10 VDC the valve is
����
open 100%.

Selection of input voltage: Upper jumper
(0 to 10 VDC), centre jumper (0 to 5
VDC) and bottom jumper (5 to 10 VDC).
By default, factory-set to upper position
(0 to 10 VDC).
Configures the short (stroke lengths of
½ inch or less), long (stroke length of
over ½ inch) stroke selection jumper. By
default, factory-set to long position (L).
Configures the direct/inverse action
jumper so that the valve shaft is in the
desired direction. By default, factory-set
to lower position, inverse action (A1).
Configures the failure position jumper. If
the signal is lost in the actuator (connec-
tion closed), the actuator, by default, will
go to the established position. Factory-
set to closed position.
