Test The Power Supply
Make sure exposed wires and bare terminals are not in contact
with other wires or grounded surfaces. Turn on the power and
measure the voltage between the
Power L
and
Power N
termi-
nals (18 and 19) using an AC voltmeter. The reading should be
between 207 and 253 V (ac).
Test The Outputs
System Pump
If a system pump is connected to the
Sys Pmp
terminal (17), make sure power to
the terminal block is off and install a jumper between the
Power L
and
Sys Pmp
terminals (18 and 17). When power is applied to the
Power L
and
Power N
ter-
minals (18 and 19), the system pump should start. If the pump does not turn on,
check the wiring between the terminal block and pump and refer to any installa-
tion or troubleshooting information supplied with the pump. If the pump operates
properly, disconnect the power and remove the jumper.
Cooling
If a cooling system is connected to the
Cooling
terminals (15 and 16), make sure power to the terminal block is off and
install a jumper between the terminals. When the cooling circuit is powered up, the cooling unit should operate. If the cool-
ing unit does not turn on, refer to any installation or troubleshooting information supplied with the cooling unit. If the cooling
unit operates properly, disconnect the power and remove the jumper.
Zone Pump or Valve
If a zone pump or valve is connected to the
Com 1-2
and
Zn 1
terminals (7 and 6),
make sure power to the pump or valve circuit is off and install a jumper between
the
Com 1-2
and
Zn 1
terminals (7 and 6). When the zone circuit is powered up,
the zone pump should turn on or the valve should open completely. If no response
occurs, check the wiring between the terminal and the pump or valve and refer to
any installation or troubleshooting information supplied with these devices.
If a zone pump or valve is connected to the
Com 1-2
and
Zn 2
terminals (7 and 8), follow a similar procedure as described
for the zone 1 relay.
If a zone pump or valve is connected to the
Com 3-4
and
Zn 3
terminals (10 and 9), follow a similar procedure as described
for the zone 1 relay.
If a zone pump or valve is connected to the
Com 3-4
and
Zn 4
terminals (10 and 11), follow a similar procedure as described
for the zone 1 relay.
If a zone pump or valve is connected to the
Com 5-6
and
Zn 5
terminals (13 and 12), follow a similar procedure as
described for the zone 1 relay.
If a zone pump or valve is connected to the
Com 5-6
and
Zn 6
terminals (13 and 14), follow a similar procedure as
described for the zone 1 relay.
Connecting The Control
Make sure all power to the devices and terminal blocks is off, and remove
any remaining jumpers from the terminals.
Reconnect the terminal blocks to the control by carefully aligning them with their
respective headers on the control, and then pushing the terminal blocks into the
headers. The terminal blocks should snap firmly into place.
Install the supplied safety dividers between the unpowered sensor inputs and the
powered 230 V (ac) or 24 V (ac) wiring chambers.
Apply power to the control. The operation of the control on power up is described in
the
Sequence of Operation
section of this brochure.
