INTRODUCTION

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.

To insure proper operation, test weekly.

STEP 3 – SELECTING THE HIGH AND LOW SET POINTS

Each limit arm is controlled by an adjustment screw. To set a limit arm,

slightly loosen the appropriate locknut (turn counter clockwise) with a

11/32” wrench (Figure 2). Next, use a screwdriver to set the limit arm to

the desired temperature limit (Figure 3).

Once the arm is in the proper setting locations, retighten the lock nut

(turn clockwise) (Figure 4). Avoid over tightening of the locknut. Repeat

this process until both temperature limits have been set. Make sure to

retighten the locknut when temp limits have been set. The TA-2HL will

not function properly if the lock nut is not retightened.

OPERATION AND TESTING PROCEDURES

To manually activate the Temp°Alert® for testing, loosen the locknut of

one limit arm and use a screwdriver to move the limit arm toward the

temperature indicator until it makes contact and temporarily tighten

the locknut nut. If installed correctly, this test procedure should activate

the warning device to which the TA-2HL is connected. After testing,

loosen the locknut, return the limit arm to its original set point and

tighten the locknut. The same test procedure should also be repeated

with the second limit arm to verify proper operation.

IMPORTANT:

Do not use the TA-1 in a cooler or freezer. Frost buildup and moisture

can cause the unit to malfunction. For cooler & freezer applications,

use an EnviroAlert® device with a remote probe.
