General

CYCLES PER HOUR (HEAT CYCLE)

The thermostat operation is based on cycles per hour. The number of cycles per hour is

adjustable through the HEAT CYCLE settings in the Adjust menu. 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 heat, the ON time is reduced.

In order to prevent short cycling of the heating relay(s), the thermostat ensures that the

relay(s) remains on or off for a minimum amount of time.

An Auto Cycle setting is available for the

heating cycle. This setting allows the

thermostat to determine the best number of

cycles per hour that balances both temperature

swings and equipment cycles.

The early start function ensures that the

zone is up to the proper temperature at the

beginning of each period. The thermostat

learns the recovery rate over multiple setback

events in order to determine the proper lead

time for the zone. If both an air sensor and

a slab sensor are used, the lead time is the

greater of the air sensor’s or the slab sensor’s

requirements.

AUXILIARY SENSORS

The thermostat has a single built-in sensor to measure air temperature at the thermostat. In

addition to the built-in sensor, the thermostat has terminals to connect up to two separate

sensors. These sensors can be either indoor sensors, slab sensors, a remote sensor, or

an outdoor sensor.

Indoor Sensor

An indoor sensor is used to measure the air temperature in the zone that the thermostat is

controlling. The temperature being read by the indoor sensor is used in the calculations of

the on times for the relay in the thermostat. Either one or both of the auxiliary sensor inputs

can be configured for indoor sensors. This setting is made through the Adjust menu of the

thermostat. If more than one sensor, either the built-in sensor or an auxiliary sensor set as

an indoor sensor, is being used to measure the zone temperature, the temperature of the

active sensors is averaged and used to calculate the on time of the relay.

Slab Sensor

A slab sensor is used to measure the slab temperature in the zone that the thermostat

is controlling. The temperature being read by the slab sensor is used in the calculations

of the on time for the Heat relay and allows the thermostat to operate the slab between

the slab minimum and slab maximum settings. If more than one slab sensor is used, the

slab temperatures are averaged by the thermostat.

Remote Sensor

A single remote sensor can be connected to the thermostat. The temperature measured

by a remote sensor does not affect the on time of the relay and is only used for display

purposes.

Outdoor Sensor

A single outdoor sensor can be connected to the thermostat. The temperature measured

by an outdoor sensor does not affect the on time of the relay and is only used for display

purposes.

ACCESS LEVELS

The tekmar Programmable Thermostat has two

access levels. These access levels restrict the

number of items available in the menus of the

thermostat. The two access levels are User and

Installer. This selection is made using the DIP

switch located on the circuit board inside the

thermostat.

The Installer access level allows the installer to

adjust all of the settings in the thermostat including

those required to match the thermostat to the

mechanical system and the devices used.

The User access level allows the end user to

adjust the time, temperatures and schedules

used by the thermostat.

Sequence of Operation

ONE STAGE HEAT

Air Sensor(s) Only Operation

When operating with only an air sensor, the on time for the Heat relay is calculated to

satisfy the requirements of the air sensor.

Slab Sensor Only Operation

When operating with only a slab sensor, the on time for the Heat relay is calculated to

satisfy the requirements of the slab sensor. The thermostat operates to maintain the slab

at the minimum slab temperature setting.

NOTE: Operating with only a slab sensor can lead to either overheating or underheating

of the space.

Air and Slab Sensor Operation

When operating with both air and slab sensors, the thermostat calculates an on time for

the Heat relay to satisfy the slab sensor’s requirements and an on time to satisfy the air

sensor’s requirements. The Heat relay operates for the longer of these two on times.

During light heating loads, overheating can occur due to the minimum slab temperature

requirements.

During heavy heating loads, the maximum slab temperature setting limits the on time of

the Heat relay. In this situation, underheating can occur.

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 or slab 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).

Installation - Slab Sensor 079

Slab Sensor 079

The tekmar Slab Sensor 079 has a stainless steel sleeve which is designed for use in

concrete, thin-set or grout. The 079 is supplied with 10’ (3 m) of 2 conductor zipcord.

STEP ONE

INSTALLING THE SENSOR

New Installations

Thin-Set or Thin-Pour Applications

If the floor covering is to be installed over either

a thin-set or thin-pour material of sufficient

depth, the 079 slab sensor can be placed

directly into either the thin-set material or the

thin-pour material and covered over. Ensure

that the sensor is located in such a position that

the attached wire is able to reach to a suitable

junction location. Splices within the thin-set or

(45 mm) long should be cut to accommodate the sensor. The sensor should be located

mid way between the heating elements to ensure a proper temperature reading.

Cables

thin-pour should be avoided to ensure trouble free operation. The sensor should be located

mid way between the heating elements to ensure a proper temperature reading.

If a thin floor covering is to be installed directly

to the subfloor, a groove 1/8” (4 mm) wide by

1/16” (2 mm) deep can be cut into the surface of

the subfloor to accommodate the wire for the

sensor. Ensure that the sensor is located in

such a position that the attached wire is able

to reach to a suitable junction location. Splices

under the floor covering should be avoided to

ensure trouble free operation. A groove 3/16”

Thick Floor Coverings (greater than 3/8” (10 mm))

If a thick floor covering is to be installed directly to the subfloor, a groove 1/8” (4 mm) wide

by 1/16” (2 mm) deep can be cut into the back of the flooring material to accommodate

the wire for the sensor. Ensure that the sensor is located in such a position that the

attached wire is able to reach to a suitable junction location.

Splices under the floor covering should be

avoided to ensure trouble free operation. A

groove 3/16” (5 mm) wide by 3/16” (5 mm)

deep by 1-3/4” (45 mm) long should be cut to

accommodate the sensor. The sensor should be

located mid way between the heating elements

to ensure a proper temperature reading.

NOTE: If it is not practical to cut a groove in the surface covering, follow the installation

method used for thin floor coverings.

Retrofit Installations

Tile Floor Coverings

If a Slab Sensor 079 is to be installed into an existing tile floor with sufficiently large grout

lines, the sensor and wire can be installed in one of the grout lines between the tiles.

located in such a position that the attached wire

is able to reach to a suitable junction location.

Splices within the grout should be avoided to

ensure trouble free operation. Remove the

appropriate grout line and place the sensor and

wire in the floor. Re-grout the area.

Subfloor

Installing the Sensor to the Bottom of a Subfloor

If the sensor is to be installed to the bottom of a subfloor, cut a piece of 1” (25 mm)

thick rigid insulation into a 6” (150 mm) by 6” (150 mm) square. A groove 3/16” (5

mm) wide by 3/16” (5 mm) deep by 1-3/4”

(45 mm) long should be cut into the insulation

to accommodate the sensor. Place the sensor

in the groove and sandwich the sensor between

the insulation and the subfloor. Use a suitable

fastening method to affix the insulation to the

subfloor.

STEP TWO

WIRING AND TESTING THE SENSOR

Caution: Do not run sensor wires parallel to telephone or power cables. If the sensor wires

are located in an area with strong sources of electromagnetic interference, shielded cable

or twisted pair should be used or the wires can be run in a grounded metal conduit.

The Slab Sensor 079 is supplied with 10’ (3 m) of cable. If a longer length is required, 24

AWG or larger wire can be spliced onto the two wires from the sensor. The splices should

be properly soldered and protected in an accessible junction box. Follow the sensor testing

instructions given in this brochure and then connect the wires to the control.

A good quality test meter capable of measuring up to 5,000 k (1 k = 1000) is required to measure the sensor resistance. In addition

to this, the actual temperature must be measured with either a good quality digital thermometer, or if a thermometer is not available, a

second sensor can be placed alongside the one to be tested and the readings compared.

First measure the temperature using the thermometer and then measure the resistance of the sensor at the control. The wires from the

sensor must not be connected to the control while the test is performed. Using the chart on the following page, estimate the temperature

measured by the sensor. The sensor and thermometer readings should be close. If the test meter reads a very high resistance, there

may be a broken wire, a poor wiring connection or a defective sensor. If the resistance is very low, the wiring may be shorted, there may

be moisture in the sensor or the sensor may be defective. To test for a defective sensor, measure the resistance directly at the sensor

location.

Do not apply voltage to a sensor at any time as damage to the sensor may result.

Sensor Testing Instructions

Thermostat Installation

NOTE: If the thermostat is to be used for remote sensing (i.e. The built-in air sensor is

disabled and an indoor sensor is being used.) Mount the thermostat in the desired location

in an appropriate manner.

STEP THREE

ROUGH IN WIRING

•

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 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

Item

Remove cover

Push tab

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. #6 1” screws

STEP FOUR WIRING THE THERMOSTAT 24 V (ac) Power

(Refer to the examples on the following pages.)

24 V (ac) power

Connect the 24 V (ac) power to the R and C terminals (1 and 2) of the thermostat. This

connection provides power to the microprocessor and display of the thermostat.

Auxiliary Sensors (S1 and S2)

Either an indoor, slab, or remote sensor may be connected to the S1 input. Connect the

two wires from the auxiliary sensor to the Com and S1 terminals (3 and 4).

Either an indoor, slab, or outdoor sensor may be connected to the S2 input. Connect the

two wires from the auxiliary sensor to the Com and S2 terminals (3 and 5).

Heat Relay

The Heat terminals (6 and 7) 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.
