Getting Started

Congratulations on the purchase of your new tekmar thermostat.

This manual will step through the complete installation, programming and sequence of operation for this control. At the back, there are tips for control and system troubleshooting.

Installation

Caution

Improper installation and operation of this control could result in damage to the equipment and possibly even personal injury or death. It is your responsibility to ensure that this control is safely installed according to all applicable codes and standards. This electronic control is not intended for use as a primary limit control. Other controls that are intended and certified as safety limits must be placed into the control circuit.

Preparation

Tools R e q u i r e d

tekmar or jeweller screwdriver

• Phillips head screwdriver

•

Materials Required

2, #6 x 1” Wood Screws

• 18 AWG LVT Solid Wire

• (Low Voltage Connections)

------------------------------------------------------

Wire Stripper•

--------------------------------------------------

Optional Adapter Plate 007 (for

• installation on 2” x 4” gang box)

Installation Location

-------------------------------------------------

Choose the placement of the thermostats early in the construction process to enable proper wiring during rough-in.

Consider the following:

Interior Wall.

• Keep dry. Avoid potential leakage onto the control.

• Relative Humidity max 80% up to 88°F (31°C) decreasing linearly to 50% RH

• at 104°F (40°C). Non-condensing environment.

No exposure to extreme temperatures beyond 32-122°F (0-50°C).

• No draft, direct sun, or other cause for inaccurate temperature readings.

• Away from equipment, appliances, or other sources of electrical interference.

• Easy access for wiring, viewing, and adjusting the display screen.

• Approximately 5 feet (1.5 m) off the finished floor.

• The maximum length of wire is 1000 feet (300 m).

• Strip wire to 3/8” (10 mm) for all terminal connections.

• Use standard 18 AWG wire for the tN2 connections.

•

Removing The Thermostat Base

To remove the thermostat base:

Place a small slot screwdriver or similar

• tool into the slot located on the top of the thermostat.

While pushing down against the plastic

• tab, pull the thermostat away from the thermostat’s base.

Mounting The Thermostat Base

If a single gang switch box is used, an Adaptor Plate 007 is required to mount the thermostat to the box.

Fasten the base of the

• thermostat to the adaptor plate.

Feed the wiring through the

• openings in the back of the adaptor plate and thermostat.

Use the upper and lower screw

• holes to fasten the adaptor plate to the box.

Thermostat Wiring

The thermostat operates a single heating system zone with two stages of heat.

Power and communication are provided to the thermostat by connecting the tN2 terminals on the thermostat to the tN2 terminals on a tN2 Wiring Center, House Control, Zone Manager or Zone Expansion Module. tN2 terminals are not polarity sensitive.

Connect the optional auxiliary sensor wires to the sensor terminals 3 and 4.

Wiring 2nd Stage Heat

-----------------------------------------------

The 529 thermostat can operate 2nd stage heat in two ways:

Method 1. Two-Stage Heating Using Wiring Center or Zone Manager

A two-stage thermostat is automatically detected when connected to Zone 1 or Zone 3 on a Wiring Center or Zone Manager. If there is no tN2 thermostat connected to Zone 2 or Zone 4, these outputs will automatically operate the heating equipment for 2nd stage heat.

Note: This 2nd stage wiring method is not compatible with the tN2 House Control 400, 401, 402, 403 and 406. Method 2 below must be used instead.

Stage 1 Stage 2 Stage 1 Stage 2

Method 2. Two-Stage Heating Using The Thermostat’s 2nd Stage Relay

If both Zone 2 or Zone 4 are in use, the 529 thermostat’s second stage relay must be used. This relay will close when the thermostat calls for 2nd stage heat (Rh-W2), and can be used to bring on the heating equipment.

Note: This 2nd stage wiring method must be used when a 529 thermostat is connected to a House Control 400, 401, 402, 403, or 406.

Testing the Thermostat Wiring

---------------------------------------------------

----------------------------------------

Testi ng the P ower

If the thermostat display turns on, this indicates that the thermostat is operating correctly and there are no electrical issues. In the event that the display is off, or the display is cycling on and off:

1. Remove the tN2 wires from the thermostat.

2. Use an electrical meter to measure DC voltage between the tN2 terminals. If the DC voltage is 0 V (dc) for 20 seconds, then there is an open or short circuit

• in the tN2 wires.

If the DC voltage is 0 V (dc) for 10 seconds and then is 23 to 24 V (dc) for 5

• seconds, this indicates the wiring is correct.

3. Connect the thermostat to the tN2 wires connected to a zone on a House Control,

Wiring Center, or Zone Manager.

4. If the thermostat display is off, or is cycling on and off, move the thermostat to the

next available zone on the House Control, Wiring Center, or Zone Manager.

If the thermostat display remains permanently on, there may be a fault with the

• previously tried zone on the House Control, Wiring Center, or Zone Manager.

If the thermostat display continues to be off, or is cycling on and off, there may

• be a fault on the thermostat.

If a fault is suspected, contact your tekmar sales representative for assistance.

Testing the Heat Zone Output

1. Press the button and set the heating temperature above the current room

temperature. Make sure the display does not show “WWSD” or “Floor Max”.

2. When the H1 symbol appears on the display, use an electrical meter to check

for voltage on the House Control, Wiring Center, or Zone Manager relay. The voltage is 24 V (ac) for zone valves, and 120 V (ac) for zone pumps when operating correctly.

---------------------------------------------------

Mounting the Thermostat

To place the thermostat back on the mounting base:

Place thermostat bottom tabs on

• matching mounting base notches.

Pivot top of the thermostat

• towards wall, ensuring wires clear obstructions.

The top clasp makes a clicking

• sound when properly closed.
