Important Safety Information It is your responsibility to ensure that this thermostat is safely installed according to all applicable codes and standards. tekmar is not responsible for damages resulting from improper installation and/or maintenance. This is a safety-alert symbol. The safety alert symbol is shown alone or used with a signal word (DANGER, WARNING, or CAUTION), a pictorial and/or a safety message to identify hazards.
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.
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 to the circuit being worked on turned off. Please be aware local codes may require this thermostat to be installed or connected by an electrician. Removing the Thermostat Base To remove the thermostat base: • Locate the tab on the bottom of the thermostat. • Push the tab with either your thumb or with a screwdriver.
If a gang box is not used: • Feed the wiring through the large hole in the thermostat base. • Mount the thermostat base directly to the wall. • Use screws in the screw holes to fasten the thermostat to the wall. At least one of the screws should enter a wall stud or similar rigid material. • Terminate wiring to the wiring strip. • Push the thermostat front onto the thermostat base. Thermostat Front Thermostat Base Stud Wall Do not over-tighten wiring screws. Hand-tighten only.
Only qualified personnel should perform testing procedures. A licensed electrician is recommended. Testing the Thermostat Wiring 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.
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 -------------------------------------------Testing the Heat W Relay 1. Set the Mode to Heat and increase the Set Heat temperature above the Room temperature. 2.

Sequence of Operation Heating Operation Set Heat Temperature -----------------------------------------------When using only a room temperature sensor, the thermostat operates the heating system to maintain the Set Heat Room temperature. The “Heat On” symbol is shown on the display when the thermostat is heating. Floor Heating-------------------------------------------------------When using both a room and a floor temperature sensor, the floor is heated at least to the Floor Minimum setting.
Cooling Operation Set Cool Temperature ----------------------------------------------The thermostat operates an air conditioner to provide cooling. The “Cool On” symbol is shown on the display when the thermostat is cooling. Cooling Cold Weather Shut Down------------------------------------When the outdoor air temperature falls below the Cooling Cold Weather Shut Down (CWSD) setting on the thermostat, the cooling system is shut off.
Hydronic System Supply Pump --------------------------------------When connected to a tekmarNet® system control, the thermostat’s W Pump setting affects the operation of the primary pump or mix pump on the system control. When the thermostat is connected to the boiler bus, the boiler system or primary pump is operated. When the thermostat is connected to the mix bus, the mix system pump is operated. If the thermostat operates a motorized or thermal motor zone valve, the W Pump setting should be set to On.
Air Group Operation To prevent heating and cooling at the same time, this thermostat can operate with other thermostats on a tekmarNet system to form an air group. The 554 can be set up as the air group master. Other heat-only thermostats can be set up as an air group member. When operating as an air group, the air temperature readings of all the air group member thermostats are communicated to the air group master thermostat and an average air temperature is determined.
Temperature Adjustment Permanent Adjustment ― No Schedule -----------------------------------When no programmable schedule is used, touch the up or down arrows to permanently set the “Set Heat Room” or “Set Cool Room” temperature. This thermostat is capable of controlling both air and floor temperature.
Programmable Schedules Energy savings can be achieved by lowering the heating temperature and increasing the cooling temperature, for example, at night, or at other times when the building is unoccupied. When operating on a programmable schedule, a or a symbol is shown in the Home menu. The or indicates the current operating temperature. All schedules are stored in permanent memory and are not affected by a loss of power.
Scenes (System Override) Scenes provide an easy way to save energy, when building residents are on vacation, for example, or override a programmable schedule when plans change. Away Key ------------------------------------------------------------------This thermostat includes an Away Key to set the thermostat to quickly turn down the heating temperatures and increase the cooling temperatures on all thermostats and suspend heating the domestic hot water tank to maximize energy savings.
Recommendation on How to Use Scenes ----------------------------Deciding how to use scenes depends on the needs and lifestyle of the customer using the building. Multi-Tenant Apartments Scenes should be disabled (None) in multi-tenant buildings where each occupant has differing heating requirements. Residential Homes Some residential customers may not require scenes. In that case, scenes can be disabled (None).
Access Levels The thermostat Toolbox menu supports four access levels: Installer (INST), User (USER), Limited (LTD), and Secure (SEC). The access level can be adjusted when the thermostat is unlocked. There are two locations to lock the thermostat: 1. Locally on the thermostat using the Lock switch located in the wiring area. 2.
