Remote Shutdown

Every Data Aire evaporator has remote shutdown contacts points available. This is 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 should have a minimum rating
of 10 amps. A minimum wire size of 18 gauge wire is recommended. Check wiring diagram for
location of the terminals.
3.7

Remote Alarm Contacts

The Mini dap4 microprocessor control panel has, a remote alarm output contact that can be fi eld
accessed on terminals #14, #15 and #16 of terminal block TB1. This is a Normally Open, Close on
Alarm, dry contact, intended to be used in a control circuit not exceeding 2 amps at 250 VAC. This
output contact will reverse position on a failure and remain reversed until the alarm is no longer present.
3.8

Remote Sensors

The Mini dap4 panel comes with remote mounted sensors for fi eld installation. The sensors are
attached to 35 feet of cable and come mounted in a remote sensor enclosure. The temperature and
humidity sensors require a total of four 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.
