557_D
tekmarNet® Thermostat 557
Installation & Operation Manual
Introduction
The tekmarNet® Thermostat 557 is a communicating touchscreen thermostat designed to operate either: a hydronic radiant floor with a two stage heat pump (water-to-air or air-to-air) for heating & cooling and an emergency backup heating system; or two stages of heating and two stages of cooling. There are three auxiliary sensor inputs that can be used to measure room, floor, outdoor or duct temperature. The optional floor sensor allows precise heating of radiant floors. Relative humidity level can be measured and controlled using either the built-in or external humidity sensor. The large touchscreen display allows you to easily adjust 7-day programmable schedules and room temperatures to optimize comfort and energy savings. The 557 can connect to tekmarNet® controls using two or four wires or it can operate as a stand-alone device.

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
Preparation
Tools Required
tekmar or jeweller screwdriver
• Phillips head screwdriver
Materials Required
18 AWG LVT Solid Wire
• (Low Voltage Connections)
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 less than 90%. 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 500 feet (150 m).
• Strip wire to 3/8" (10 mm) for all terminal connections.
• Use standard 8 conductor, 18 AWG wire.
------------------------------------------------------
Wire Stripper
--------------------------------------------------
-------------------------------------------------
Do not use in the presence of ammonia (barn animals), methanol, ethanol
• or acetone. Damage to the internal sensor may result.

To prevent the risk of personal injury and/or death, make sure power is not applied to the thermostat until it is fully installed and ready for final testing. All work must be done with power turned off to the circuit being worked on.
Please be aware local codes may require this thermostat to be installed or connected by an electrician.
Removing The Wiring Cover
To remove the thermostat’s wiring cover:
Locate the slotted hole on the right
• side of the thermostat.
Insert a screwdriver in the slotted hole
• to depress the latch.
Remove the wiring cover from the
• thermostat.
Mounting The Thermostat
If a single gang box is used:
Feed the wiring through the large
• holes of the thermostat.
Fasten the base of the thermostat to
• the gang box using two screws.
Terminate wiring to the wiring strip.
• Re-install the wiring cover.

Thermostat Wiring
------------------------------------------
The thermostat operates a single heating system zone and can be wired in three different ways.
Stand Alone
- Similar to tekmarNet®4 wiring with tN4 wiring terminal not used. First
stage heating relay (Rh1 - W1) can be wired directly to switching relays. tekmarNet®4 - Allows the thermostat to be wired using 4 wires to a tN4 Wiring Center
or Zone Manager point-to-point. Alternatively, the thermostat can operate the heating and cooling equipment locally and the tN4 communication bus can be daisey-chained from one thermostat to another.
®
tekmarNet
2 - Allows the thermostat to be wired point-to-point using 2 wires to a tN2
Wiring Center, House Control, or Zone Manager. This allows easy wiring for retrofit applications.
Application specific wiring diagrams are provided in the 557_A brochure.
Compatible Sensors
The thermostat is compatible with Indoor Sensor type 076, 077, 084, Slab Sensor type 072, 073, 079, Outdoor Sensor type 070, Duct Sensor type 083 and Humidity & Temperature Sensor type 086.
Testing the Thermostat Wiring
Only qualified personnel should perform testing procedures. A licensed electrician is recommended.
Testing tekmarNet®2 Wiring
------------------------------------------
Testing the Power
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 thermostat wiring cover.
2. Check to ensure that the tN2 wires on the thermostat are connected to a zone on a House Control, Wiring Center, or Zone Manager.
3. Use an electrical meter to measure DC voltage between the tN2 terminals.
If the DC voltage is 0 V (dc) for at least 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.

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 tekmarNet®4 and Stand Alone Wiring
Testing the Power
1. Remove the front cover from the thermostat.
2. Use an electrical test meter to measure (ac) voltage between the R and C terminals.
The reading should be 24 V (ac) +/– 10%.
3. Install the front cover.
Testing the Relay Outputs
The thermostat includes a User Test to check if the thermostat’s relays are operating and that the thermostat is wired correctly to the HVAC equipment. The User Test setting can be located in the Toolbox menu. Either Heat or Cool test can be selected.
Cancel button - Exits the user test and returns the Toolbox menu. Hold button - Pauses the user test step for up to 5 minutes. Next Item button - Advances the user test to the next test step.
