Thank you for your purchase of the Winland Temp°Alert® model TA-2HL. Your new TA-2HL has been designed for
reliable monitoring of non-condensing (indoor only) environment areas where high and low temperature limits

are critical. This unit will separately zone out high and low temperature alarm signals. This unique feature enables you
to instantly identify whether your facility being monitored has a high or low temperature condition.

Simply select an acceptable temperature range by setting the adjustable high and low limit stops. If temperature in
the monitored area either rises or falls to the limit stops, the temperature indicator will contact one of the limit stops.
This completes the circuit and provides you with a dry contact alarm signal. The TA-2HL contacts are normally open
dry contacts rated at 50 mA at 12 VDC. This output can be used to activate alarm systems, telephone dialers, or other
remote warning devices. The TA-2HL is the ideal addition for any security system.

LOCATION

In specifying the location and number of Temp°Alerts® to install consider room size, effectiveness of the ventilation
system, and critical monitoring areas. If the building already has an energy management system, an easy rule of
thumb to follow is to install a TA-2HL near each thermostat. It should be mounted on a wall or other vertical surface in
the area where temperature is to be monitored. Make sure it is well clear of windows, doors, or heat sources that could
cause an inaccurate reading of air temperature. When protecting a building against freeze damage, always install at
least one TA-2HL on every level of the home or business.

INSTALLATION

Tools needed:

• Standard screwdriver

• 11/32” wrench

• 22-18 AWG twisted pair (optional)

STEP 1 – ATTACH TEMP°ALERT® TO MOUNTING SURFACE

After you have determined a location for the device to be mounted, position the attached template in the mounting
location and mark the mounting holes with a pen or other marking device. Depending on the type of surface you
are mounting to, you may need to pre-drill holes to accept the mounting screws alone, or the plastic anchors and
mounting screws. Drive the screws into the mounting surface, allowing approximately 3/16” between the screw head
and the mounting surface. Engage the key slots on the back of the TA-2HL case with the screw heads and press down.

STEP 2 – MAKING THE WIRING CONNECTIONS

Attach the connecting cable to any two open zones on any
alarm panel, telephone dialer, wireless transmitter, etc.
See Figure 1 for an example of the proper wiring sequence
utilizing an alarm system.

If desired, the green and black wires on the connection
cable may be connected together under a single zone. This
is useful whenever a limited number of open zones are
available and you do not wish to differentiate between a
high and low temperature notification.
