WINLAND MTA-2 TempAlert Mechanical Temperature Monitor
This package contains
- mounting screws and 2 anchors
- Installation/Operating Instructions Guide
- MIIA-2
Location
In specifying the location and number of Temp Alerts to install, consider room size, effectiveness of the ventilation system, and critical non-condensing (indoor only) environment monitoring areas. If the building already has an energy management system, an easy rule of thumb to follow is to install the MTA-2 near each thermostat. It can 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 inaccurate reading of air temperature. When protecting a building against freeze damage, always install at least one Temp Alert” on every level of the home or business.
Installation
- Standard screwdriver
- 5/16″ wrench or nut driver
- 22-18 AWG twisted pair
Opening the Case
Begin with the device facing you. Turn the device 90 to the right to expose the left end of the case. Notice the left end of the base plate has been tooled with a single attachment hole, whereas the right end has not. Grasp the device with your right hand, position your thumb on the center of the left end of the device above the seam with your remaining fingers on the right end of the device (See Figure 1). Press hard with your thumb to disengage the latching pin. Separate the two halves by pulling the device away from the base plate.
To open the case, squeeze firmly with your thumb and pull front face plate away from the back plate.
Attach Base Plate to Mounting Surface
After you have determined a location for the device to be mounted, position
the base plate of the device on the mounting surface with your hand and mark
the center point of the mounting holes with a pen or other marking device.
Mount the base plate to the wall using the included mounting screws. Depending
on the type of surface you are mounting to, you may need to predrill holes to
accept the mounting screws alone, or the plastic anchors and mounting screws.

Select the High and Low Set Points
Each limit post is controlled by a locknut. Use a 5/16″ nut driver or wrench
to loosen (turn counterclockwise) the high and low adjustment posts (See
Figure 2). After loosening, slide the posts to the proper temperature setting.
Once the posts are in the proper setting locations, simply retighten the lock
nuts (turn clockwise). Avoid over tightening of the locknut.

Making the Wiring Connections
To complete the installation, use three conductor stranded or solid wire to
connect the MTA-2 to a control panel, dialer, etc. See Figure 3 for an example
of a standard installation that utilizes differentiated notification outputs
for high and low temperature occurrences. If desired, the HI limit wire and
LOW limit wire 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.
Attach Front Cover to Base Plate
Grasp the device with your right hand by positioning your thumb on the center
of the left end of the device above the locking pin and positioning your
remaining fingers on the right end of the case (See Figure 1). Align the
retaining tabs on the right edge of the case with the holes on right edge of
the base plate currently attached to the mounting surface. Press hard with
your thumb on the left end of the device and swing the device back toward the
base plate until the device seats properly into the base plate and the locking
pin engages.
Operation and Testing Procedures
To manually activate the MTA-2 for testing, loosen the locknut of one limit
post and slide it 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 MTA-2 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 MTA-2 in a cooler or freezer. Frost buildup and moisture can
cause the unit to malfunction. For cooler and freezer applications, use an
EnviroAlert or EnviroAlert Professional device with a remote probe.
