Sequence of Operation Section A Heat and Cool Applications The 553 can operate in several different combinations of conventional and heat pump applications.
Warm Weather Shut Down-------------------------------------------------------------------When the outdoor air temperature exceeds the Warm Weather Shut Down (WWSD) setting on the tekmarNet® main control, the heating system is shut off. A W HEAT WWSD setting is available to allow a forced air heating system to heat the building while the radiant floor heat system is shut off during mild outdoor temperatures.
The first stage operates on a temperature differential of ±0.7°F (±0.4°C) centered around the heating setpoint. The second stage heat turns on when the temperature drops 0.7°F - W2 Differential setting below the heating setpoint. The second stage is shut off once the temperature reaches the heating setpoint. The second stage W2 is prevented from turning on until the first stage heat W or the heat pump operates for the elapsed time set by the W2 Delay setting. Auto provides the shortest wait time.
Section E Mode Operation The thermostat includes a mode key. Available modes are: • Heat - Allows heating • Cool - Allows cooling • Auto - Automatically switches between heating and cooling as necessary. The interlock time is applied when switching from heating to cooling or from cooling to heating. • Emergency - Only available when operating a heat pump. When set to Emergency the heat pump is locked out and the hydronic and backup heat are operated.
Section G Fan Operation The fan operates together with the air heating or cooling systems. The user can also select to operate the fan manually by pressing the Fan button. This allows the user to choose between Auto and On. “Auto” allows the fan to operate together with heating or cooling but normally the fan is off. “On” forces the fan to operate continuously.
The thermostat has three humidification modes. Mode Operation HM1 Stand Alone Humidifier Humidifier operates independently of the HVAC system. Available in all modes except off. HM2 Humidifier with Fan Humidifier ducted together with HVAC system. The system fan is operated whenever the humidifier is operating. This is only available when operating a conventional heating system with a fan. Available in all modes except off. HM3 Humidifier with Air Heating Humidifier ducted together with HVAC system.
Section I Air Group Operation In order to prevent heating and cooling at the same time, this thermostat can operate together with other thermostats on a tekmarNet® system to form an air group. On older model thermostats the air group functionality was previously described as a cool group. In an air group, one thermostat is assigned as the air group master. The air group master operates both the air heating and cooling equipment for the group. The 553 can be set to be a master or a member of the air group.
Section K 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.
Section L Programmable Schedules Energy savings can be achieved by lowering the heating temperature and increasing the cooling temperature when the building is unoccupied or during the night. 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.
Section M Scenes (System Override) Scenes provide an easy way to save energy while away on vacation, or override a programmable schedule when plans change. --------------------------------------------------------------Away Key -----------------------------------This thermostat includes an Away Key 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 -----------------------------------Choosing 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 which case, scenes can be disabled (None).
Section O 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.
Troubleshooting Error Messages (1 of 5) Error Message Description SETUP MENU SAVE ERROR The thermostat failed to read the Setup menu settings from memory and has reloaded the factory default settings. The thermostat stops normal operation until all settings in the Setup menu are checked except to provide freeze protection. To clear the error, set the access level to Installer and check all settings in the Setup menu.
Error Messages (2 of 5) Error Message Description DISPLAY MENU SAVE ERROR The thermostat failed to read the Display menu settings from memory and has reloaded the factory default settings. The thermostat continues to operate normally while displaying this error. To clear the error, set the access level to Installer and check all settings in the Display menu. tN2 PORT ERROR The thermostat has been connected to a tN2 zone already in use by a 2-stage zoning control.
Error Messages (3 of 5) Error Message Description DEVICE LIMIT More than 24 devices (thermostats or setpoint controls) have been connected to the tekmarNet® communication bus. To clear the error, remove and relocate devices to other available buses until the device count is 24 or less. ROOM SENSOR SHORT CIRCUIT ERROR Due to a short circuit, the thermostat is unable to read the built-in room temperature sensor.
Error Messages (4 of 5) Error Message Description SYSTEM CONTROL LOST ERROR The thermostat can no longer communicate to the tekmarNet® system control. Check for open or short circuits in the tekmarNet® communication wiring. The error automatically clears once the tekmarNet® system control has been detected. If the tekmarNet® system control was intentionally removed from the thermostat, remove and then re-apply power to clear the error.
Error Messages (5 of 5) Error Message Description ERROR AT THERMOSTAT There is an error on a different thermostat or setpoint control connected to the tekmarNet® system and not on this thermostat. 01 to 24 = Thermostat only network Go to the thermostat with the listed address to correct the error. ERROR AT THERMOSTAT There is an error on a different thermostat or setpoint control connected to the tekmarNet® system and not on this thermostat.
