Check the wiring connections in the unit control panel to ensure they are tight. Screw
terminals may become loose in transit. Tightening of all wiring connections is the
responsibility of the installing contractor.
3.6 Remote Shutdown
Every Data Aire evaporator has remote shutdown contact points available. These are intended for
a fi eld supplied 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. Remove this
wire prior to installing the fi eld wires.
3.7 Remote Alarm Contacts
3.7.1 If the optional Mini DAP® II microprocessor control panel is ordered with the optional summary
alarm module, a remote alarm 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 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 terminals #11 (common)
and #12 (normally closed) or #13 (normally open) of terminal block TB1. This is a normally open or
normally closed, dry contact, will reverse position upon alarm and is intended to be used in a control
circuit not exceeding 5 aps 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 The optional Mini DAP II panel normally comes with sensors mounted in the panel. Although
these existing sensors can be removed for remote mounting, the remote sensor option provides a
more convenient means of fi eld installation. This is because the sensors are already connected to
a predetermined length of cable and come mounted in a remote sensor enclosure. The temperature
and humidity sensors require a total of six wires. This should be a twisted, shielded cable.

these existing sensors can be removed for remote mounting, the remote sensor option provides a
more convenient means of fi eld installation. This is because the sensors are already connected to
a predetermined length of cable and come mounted in a remote sensor enclosure. The temperature
and humidity sensors require a total of fi ve wires. This should be a twisted, shielded cable.
3.9 Condensate Pumps
Condensate pumps which ship loose normally require a separate source of 110 volt power. Always
check the pump power requirements before connecting power. Condensate pumps are available
in other voltages.
Condensate pumps may also come unit mounted and wired in the unit as a factory option. While no
outside power source is required, fi eld piping is still a requirement.
