Condensing units (compressors mounted in the condenser) typically require more wires. Refer to
the wiring diagrams in the unit.
WARNING: Check the wiring connections in the unit control panel to ensure
they are tight. Screw terminals may become loose in transit. Tightening of
wiring connections is the responsibility of the installing contractor.
3.6 Remote Shutdown
Every Data Aire evaporator has remote contact points available. These are intended for a fi eld sup-
plied dry contact or switch to be wired across two terminals. When the contact or switch opens, the
control circuit power is interrupted and the unit shuts down, including the control panel. The control
circuit is 24 VAC and the fi eld provided contact or switch and wiring should have a minimum rating
of 10 amps. A minimum of 18 gauge wire is recommended.
The remote shutdown contacts are always terminals #1 and #2 on the terminal block designated
TB1. The unit is shipped with a factory jumper wire that connects terminal #1 to terminal #2. Re-
move this wire prior to installing the fi eld wires.
3.7 Remote Alarm Contacts
3.7.1 Mini DAP-II Units
If the unit has the optional Mini DAP-II microprocessor control panel and optional summary alarm
module, a remote output contact can be fi eld accessed on terminals #14 and #15 of terminal block
TB1. This is a normally Open (Close on Alarm) dry contact intended to be used in a control circuit
not exceeding 5 amps at 24 VAC. This output contact will close on a failure and remain closed until
the alarm is no longer present.
3.7.2 Mini DAP-III Units
If the optional Mini DAP-III microprocessor control panel is ordered with the optional summary alarm
module, a remote alarm output contact can be fi eld accessed on terminal #11 (common) and #12
(normally closed) or #13 (normally open) of terminal block TB1. This is a normally open or normally
closed contact that will reverse position upon alarm and is intended to be used in a control circuit
not exceeding 5 amps at 24 VAC. This output contact will reverse position on a failure and remain
reversed until the alarm is no longer present.
3.8 Remote Sensors
3.8.1 Mini DAP-II Units
The optional Mini DAP-II microprocessor control panel normally comes with sensors mounted in
the panel. Although these existing sensors can be removed for remote mounting, the remote sen-
sor option provides a more convenient means of fi eld installation. When ordered, the remote sen-
sors are shipped with a predetermined length of cable and come mounted in a plastic enclosure.
The temperature and humidity sensors require a total of six wires. These wires should be twisted,
shielded type.
