ACCESSORY CONNECTIONS — Terminal labeled A on
the control is provided to control accessory devices such as
water valves, electronic air cleaners, humidifiers, etc. This sig-
nal operates with the compressor terminal. See Fig. 8. Refer to
the specific unit wiring schematic for details.
NOTE: The A terminal should only be used with 24-volt
signals — not line voltage signals.
WATER SOLENOID VALVES —
Water solenoid valves
may be used on variable flow systems and ground water instal-
lations. A typical well water control valve wiring which can
limit waste water in a lockout condition is shown in Fig. 8. A
slow closing valve may be required to prevent water hammer.
When using a slow closing valve, special wiring conditions
need to be considered. The valve takes approximately 60 sec-
onds to open (very little water will flow before 45 seconds) and
it activates the compressor only after the valve is completely
opened by closing its end switch. When wired as shown, the
valve will have the following operating characteristics:
1. Remain open during a lockout.
2. Draw approximately 25 to 35 VA through the “Y” signal
of the thermostat.
PRE-START-UP
System Checkout —
When the installation is complete,
follow the System Checkout procedure outlined below before
starting up the system. Be sure:
1. Voltage is within the utilization range specifications of the
unit compressor and fan motor, and voltage is balanced
for 3-phase units.
2. Fuses, breakers and wire are correct size.
3. Low voltage wiring is complete.
4. Piping and system flushing is complete.
5. Air is purged from closed loop system.
6. System is balanced as required. Monitor if necessary.
7. Isolation valves are open.
8. Water control valves or loop pumps are wired.
9. Transformer switched to lower voltage tap if necessary.
10. Service/access panels are in place.
11. Control field-selected settings are correct.
FIELD SELECTABLE INPUTS
Jumpers and DIP (dual in-line package) switches on the
control board are used to customize unit operation and can be
configured in the field.
Complete C Control Jumper Settings (See
Fig. 6A-6C)
WATER COIL FREEZE PROTECTION (FP1) LIMIT
SETTING — Select jumper 3, (JW3-FP1 Low Temp) to
choose FP1 limit of 10 F or 30 F. To select 30 F as the limit,
DO NOT clip the jumper. To select 10 F as the limit, clip the
jumper.
ALARM RELAY SETTING — Select jumper 1 (JW1-AL2
Dry) for connecting alarm relay terminal (AL2) to 24 vac (R)
or to remain as a dry contact (no connection). To connect AL2
to R, do not clip the jumper. To set as dry contact, clip the
jumper.
Complete C Control DIP Switches —
The
Complete C Control has 1 DIP switch block with five
switches. See Fig. 6A-6C.
PERFORMANCE MONITOR (PM) — DIP switch 1 will
enable or disable this feature. To enable the PM, set the switch
to ON. To disable the PM, set the switch to OFF.
STAGE 2 — DIP switch 2 will enable or disable compressor
delay. Set DIP switch to OFF for stage 2 in which the compres-
sor will have a 3-second delay before energizing. DIP 3 is not
used. DIP 4 is not used. DIP switch 5 is used to initiate 1 or
3 tries for the FP1 fault. If water freeze protection for the water
coil then DIP switch 5 can be set to lockout on the FP1 fault
after 1 try.
Deluxe D Control Jumper Settings (See
Fig. 6D and 6E)
WATER COIL FREEZE PROTECTION (FP1) LIMIT
SETTING — Select jumper 3, (JW3-FP1 Low Temp) to
choose FP1 limit of 10 F or 30 F. To select 30 F as the limit,
DO NOT clip the jumper. To select 10 F as the limit, clip the
jumper.
ALARM RELAY SETTING — Select jumper 4 (JW4-AL2
Dry) for connecting alarm relay terminal (AL2) to 24 vac (R)
or to remain as a dry contact (no connection). To connect AL2
to R, do not clip the jumper. To set as dry contact, clip the
jumper.
IMPORTANT: Two-compressor units with Complete C or
Deluxe D controls wired to terminal A will be turned off if
the controls are in lockout mode, even if the other board is
in normal operating mode.
IMPORTANT: This can overheat the anticipators of
electromechanical thermostats. Only use relay based
electronic thermostats.
IMPORTANT: Jumpers and DIP switches should only
be clipped when power to control board has been turned
off.
