Display / Keypad Operation

The thermostat’s display has four distinct fields. These fields are the Menu field, the Item field,
the Number field and the Status field. The four buttons on the face of the thermostat are used
to navigate through the menus and items to view and / or adjust the desired settings.

General

CYCLES PER HOUR

The thermostat operation is based on cycles per hour. During each cycle that heating is required,
the thermostat turns on the Heat relay for a calculated amount of time. This amount of time is
the “ON time”. The ON time is calculated based on the requirements of the zone. If the zone
requires more heating, the ON time is increased. If the zone requires less heating, the ON time
is reduced.

In order to prevent short cycling of the heating relay,

Cycles Per Hour

the thermostat ensures that the relay remains on or
off for a minimum amount of time.

The 507 Thermostat has an Auto Cycle. This allows
the thermostat to determine the best number of

cycles per hour that balances both temperature
swings and equipment cycles.

Sequence of Operation

MODE

Heat

In the heat mode, the Heat relay is operated to satisfy the temperature requirement of the
zone.

Off

In the OFF mode, the Heat relay is not operated.

NOTE: If an air sensor is active in the OFF mode, a freeze protection is enabled that allows
the Heat relay to be operated to keep the zone above 35°F (2°C).

STEP ONE

Check the contents of this package. If any of the contents are missing or damaged, please
contact your wholesaler or tekmar sales representative for assistance.

Type 507 Includes:

GETTING READY

• One Thermostat 507 •• Data Brochure D 507 • User Brochure U 507

STEP TWO

REMOVING THE FRONT COVER

Place a screwdriver or similar object into the small
slot located in the top of the thermostat. Push the
screwdriver against the plastic tab and pull the top of
the front cover so that it pivots around the bottom edge
of the base.

STEP THREE

MOUNTING THE BASE

The thermostat should be installed on an interior wall
of the desired zone approximately 5’ (1.5 m) above
the floor. Do not mount the thermostat 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 thermostat to prevent air from
blowing through the wiring hole and affecting the
thermostat’s built-in sensor.

Mount the base 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 the
thermostat is to be mounted to a 2” x 4” electrical
box, order an Adaptor Plate 007. This plate mounts
to the electrical box and the thermostat mounts to
the plate. Ensure that the electrical box does not
provide cold air to the thermostat.

STEP FOUR

18 AWG or similar wire is recommended for all 24 V (ac) wiring.

All wires are to be stripped to 1/4” (6 mm) to ensure proper connection to the control.

Run wires from the 24 V (ac) power to the thermostat. Use a clean power source to

ensure proper operation.

Run wires from the heating device to the thermostat.

STEP FIVE

WIRING THE THERMOSTAT

(Refer to the examples on the following page.)

24 V (ac) Power

Connect the 24 V (ac) power to the R and C terminals of the thermostat. This connection
provides power to the microprocessor and display of the thermostat.

Heat Relay (Rh - W)

The Heat Relay Rh - W terminals are an isolated output. There is no power available
on these terminals from the thermostat. These terminals are to be used as a switch for
a 24 V (ac) circuit. This circuit can operate a low current 24 V (ac) device directly or an
external relay to enable a line voltage or high current device.

STEP SIX

INSTALLING THE FRONT COVER

Align the hinges on the bottom of
the front cover with the bottom of the
thermostat mounting base. Pivot the
front cover around the bottom hinges
and push the top against the mounting
base until it snaps firmly in place.

Limited Warranty and Product Return Procedure

Limited Warranty The li ability of t ekmar u nder this wa rra nty is li mit ed. The Purchas er, by taking r eceipt of

any tekmar product (“Product”), acknowledges the terms of the Limited Warranty in effect at the time of
such Product sale and acknowledges that it has read and understands same.

The tekmar Limited Warranty to the Purchaser on the Products sold hereunder is a manufacturer’s pass­through warranty which the Purchaser is authorized to pass through to its customers. Under the Limited
Warranty, each tekmar Product is warranted against defects in workmanship and materials if the Product
is installed and used in compliance with tekmar’s instructions, ordinary wear and tear excepted. The pass­through warranty period is for a period of twenty-four (24) months from the production date if the Product is
not installed during that period, or twelve (12) months from the documented date of installation if installed
within twenty-four (24) months from the production date.

The liability of tekmar under the Limited Warranty shall be limited to, at tekmar’s sole discretion: the cost of par ts
and labor provided by tek mar to repair defects in materials and/or workmanship of the defective product; or to the
exchange of the defective product for a warranty replacement product; or to the granting of credit limited to the
original cost of the defective product, and such repair, exchange or credit shall be the sole remedy available from
tekmar, and, without limiting the foregoing in any way, tekmar is not responsible, in contract, tort or strict product
liability, for any other losses, costs, expenses, inconveniences, or damages, whether direct, indirec t, special, sec­ondar y, incidental or c onsequential, arising from ownership or use of the product, or from defects in workmanship
or materials, including any liability for fundamental breach of contract.

The pass-through Limited Warranty applies only to those defective Products returned to tekmar during the war­ranty period. This Limited Warranty does not cover the cost of the par ts or labor to remove or transport the defec­tive Product, or to reinstall the repaired or replacement Product, all such costs and expenses being subject to
Purchaser’s agreement and warrant y with its customers.

Any representations or warranties about the Products made by Purchaser to its customers which are different from
or in excess of the tekmar Limited Warranty are the Purchaser’s sole responsibility and obligation. Purchaser shall
indemnify and hold tekmar harmless from and against any and all claims, liabilities and damages of any kind or

the territory in which such Product is located. If tekmar receives an inquiry from someone other than a tekmar
Representative, including an inquiry from Purchaser (if not a tekmar Representative) or Purchaser’s customers,
regarding a potential warrant y claim, tekmar’s sole obligation shall be to provide the address and other contact
information regarding the appropriate Representative.
