Room Temperature Unit (RTU) 062
The tekmar Room Temperature Unit (RTU) 062 consists of an air temperature sensor, a
liquid crystal display (LCD) and four buttons. These buttons and the LCD are used to set
and view the desired room temperature. The RTU’s LCD displays the current
room temperature, the outdoor air temperature and a number of other items.
The 062 can only be used with tekmar controls that are tekmar Net™capable (tN1 or
tN1/tN2) terminals. The items that the 062 displays depends on the type of tekmar control
that the RTU is connected to. To determine the exact items that are displayed by the
RTU, refer to the Data Brochure for the control that the 062 is to be used with. In cases
where a restricted temperature range is required, the RTU’s range can be limited by
changing the access level of the RTU.
Room Temperature Unit (RTU) 063
The tekmar Room Temperature Unit (RTU) 063 consists of one internal air sensor, three
remote temperature sensor inputs, a liquid crystal display (LCD) and four buttons. These
buttons and the LCD are used to set and view the desired room temperature. The RTU’s
LCD displays the current room temperature, the outdoor air temperature, temperatures
at the remote air or slab sensors, and a number of other items.
The 063 can only be used with tekmar controls that are tekmar Net
™ capable (tN1 or
tN1/tN2 terminals). The items that the 063 displays depends on the type of tekmar control
that the RTU is connected to. To determine the exact items that are displayed by the
RTU, refer to the Data Brochure for the control that the 063 is to be used with.
In cases where a restricted temperature range is required, the RTU’s range can be limited
by changing the access level of the RTU.
Installation
STEP ONE REMOVING THE FRONT COVER
Place a small screwdriver or similar object into the small slot located in
the top of the RTU enclosure. Push the screwdriver down against the
plastic tab and pull the top of the front cover so that it pivots around the
bottom edge of the RTU. The back cover provides the base to which the
front of the RTU mounts. Store the front of the RTU in a safe place until
wiring must be completed.

STEP TWO MOUNTING THE RTU
The RTU should be installed on an interior wall of the desired zone to be
controlled. Do not mount the RTU in a location that may be affected by
localized heat sources or cold drafts. It may be necessary to install a draft
barrier behind the enclosure in order to prevent air from blowing through the
wiring hole and affecting the RTU reading.
Mount the RTU directly to the wall using two #6-1”screws. The screws are
inserted through the mounting holes and must be securely fastened to the
wall. If possible, at least one of the screws should enter a wall stud or similar
surface. If local code requires that the RTU be mounted to a 2”x 4”electrical
box, order an Adapter Plate 007. This plate will mount to the electrical box
and the RTU will then mount to the plate. Ensure that the electrical box does
not provide cold air to the RTU.
STEP THREE WIRING THE RTU
Run 18 AWG twisted pair or similar wire between the RTU and the control.
Insert the wires through the hole provided in the back of the RTU enclosure
and connect them to the Com and the tekmar NetTM (tN1) terminals. Do not
run the wires parallel to telephone or power lines as this may interfere with
the operation of the RTU. If the RTU wires are located in an area with strong
sources of electromagnetic noise, shielded cable should be used or the
wires can be run in a grounded metal conduit.
NOTE: Do not apply power to the RTU. The RTU is powered by the
control. The connection between the control and the RTU is polarity
sensitive. The Com terminal of the RTU must be connected to the Com
terminal of the control and the tekmar Net
TM
(tN1) terminal of the RTU
must be connected to the appropriate tekmar Net
TM
(tN1) terminal of
the control. If the wires are reversed, the display on the RTU will
remain blank and the control will display a short circuit error for the
tekmar Net
TM
(tN1) device.
STEP FOUR REMOTE SENSORS TO THE 063
Remote indoor sensors can be connected to the 063 to average the air
temperature reading. Typically, multiple remote sensors are used in large
open areas in a building to get an average indoor air temperature. Any type
of tekmar 10K sensor can be connected to the input(s) on the 063.
Room or Slab Temperature Control using a Slab Sensor
The RTU 063 can be configured for slab and air temperature control
using a slab sensor connected to the Rs3 and Com terminals (3 & 5) and
the air sensor in the RTU. The control that the 063 is connected to must
be configured to support this feature. The minimum and maximum slab
temperature and air temperature settings are adjusted at the RTU.
If the air temperature sensor at the RTU is turned off, the air temperature
is ignored.

Averaging Slab Temperature
The slab sensor can only be connected to the Rs3 input
on the 063. If you wish to average slab temperatures,
connect slab sensors in a series / parallel arrangement
as shown. The 063 will see one average slab temperature
and respond accordingly. Refer to Data Brochure D 071A
for multiple sensor wiring arrangements.
STEP FIVE INSTALLING THE FRONT COVER
Align the hinges on the bottom of the front cover with the bottom of the RTU mounting base.
Pivot the front cover around the bottom hinges and push the top against the mounting base
until it snaps firmly in place.
View Menu
When in the view menu, press either the Up or Down button to adjust the desired
room temperature. The temperature being adjusted depends on whether the control is
in the Occupied or UnOccupied mode. Refer to the control’s Data Brochure for available
items.
Adjust Menu
Use the Menu button to select the Adjust menu. In the Adjust menu, use the Item button to select the item to adjust, then use either
the Up or Down buttons to adjust it. Refer to the control’s Data Brochure for available items.
Temperature Units
The RTU is capable of displaying the temperature in either ˚F or ˚C. In order to select the temperature units, press the Menu button
until the Miscellaneous ( Misc ) menu is displayed. Then, while the UNITS item is displayed, use the Up or Down button to select the
desired units of measure.
Access Levels
The RTU has four access levels that restrict the number of Menus, Items, and Adjustments that can be accessed by the user. The
four access levels are Limited (LTD), User (USER), Installer (INST), and Advanced (ADV).
The access level of the RTU is found in the Miscellaneous (
Misc ) menu. The access level can only be viewed and / or adjusted when
the Lock / Unlock DIP switch of the control that the RTU is connected to is set to the Unlock position. To determine if the RTU’s access
level is currently locked or unlocked, a small segment representing a padlock is viewed in the bottom right hand corner of the display.
Limiting the Temperature Range
The adjustment range of the desired room temperature can be limited in order to avoid extreme temperature settings. Set the desired
room temperature in the Adjust menu. Then go to the Miscellaneous ( Misc ) menu and select the LTD access level. If desired, set the
Lock / Unlock DIP switch on the control to the Lock position so that the access level can no longer be adjusted.
As long as the RTU remains in the LTD access level the room temperature setting(s) can only be adjusted ±3 ˚F ( ±1 ˚C) from the setting
that was selected when the RTU was placed into the LTD access level.
