Access Levels The Access Level restricts the number of Menus, Items and Adjustments that can be accessed by the user. The Access Level setting is found in the Miscellaneous (MISC) menu. Select the appropriate access level for the people who work with the setpoint control on a regular basis.
User Interface Use the User Interface available on the Liquid Crystal Display (LCD) to setup and monitor the operation of the setpoint control. Use the four push buttons below the LCD (Menu, Item, Up, Down) to select settings. As the settings are entered, record the settings in the Job Record J 162. Menu The menus display in the Menu Field at the left of the LCD. Item In each menu, a group of items can be selected. The abbreviated name of the selected item displays in the Item field of the LCD display.
Application Overview The Setpoint Control 162 is designed to support six different applications. The items shown in the VIEW and ADJUST Menu change depending on the Application Mode. Set the application mode as follows: The VIEW and ADJUST menus list which of the six application items are visible based upon the mode column. The TIME, SCHD (Schedule) and MISC (Miscellaneous) menus are the same for the six application modes.
Applications: Pulse Width Modulation Mode 4 Setpoint (PWM) Relay 1 Pulse Width Modulation (PWM) Operation PWM operates by centering the throttling range around the target setpoint temperature. PWM is best suited for large heating or cooling loads that do not change rapidly in temperature. The Differential setting in the ADJUST menu changes the throttling range while in Application Mode 4 (Setpoint). The throttling range is not adjustable in Application Modes 5 (Floor) or 6 (Pool).

Sequence of Operation Application Mode 1 - On / Off Setpoint SECTION A Application Mode 1 is a generic setpoint control operation using an on/off differential for heating or cooling. The sensor is required to be located at the temperature control point. The setpoint control can have an occupied, unoccupied, and away temperature setting. Relay 2 Operation Relay 2 operates continuously while in the occupied period to provide constant circulation and reduce temperature swing.
Occupied Time The setpoint control can temporarily override the scheduled temperature and operate at the occupied temperature on a timer. To cancel the temporary occupied time, press and hold the Down button until the display shows OFF, at which point, the setpoint control returns to the schedule. Press the Up or Down buttons while in the View menu to set the amount of time that the occupied temperature should remain in effect.
Application Mode 5 - Floor SECTION E Application Mode 5 configures the setpoint control for floor warming and floor heating applications using pulse width modulation. Floor warming is not necessarily designed to heat the room, but to make the floor feel warm to the touch. This is common especially in bathrooms. For bathroom applications, Relay 2 can also heat a towel warmer radiator while in the occupied period. A sensor must be located within the slab between the heating pipes.
Cycle Length SECTION G Select the heating or cooling cycle length in minutes for Application Modes 4 (Setpoint), 5 (Floor), and 6 (Pool). The cycle length is the total on time and off time of Relay 1. This helps prevent short cycling. The following settings are available: CTRL = The cycle length is the same as the tN4 system control. This is the factory default. SYNC = The cycle length synchronizes with other thermostats and setpoint controls that have also been set to the SYNC setting.
Sensor Input SECTION J The Setpoint Control 162 requires a temperature sensor (Universal Sensor 071 included) to be connected to the sensor input on the back of the control. All tekmar sensors are compatible. Choose the sensor type that best meets the requirements of the application. See application mode diagrams for the recommended location of the sensor. Time Clock SECTION K The setpoint control has a built-in time clock to allow the control to operate on a programmable schedule.
Schedule Mode 4 events per day An event is a time at which the thermostat changes the set temperature. The event time can be set to the nearest 10 minutes. If you wish to have the thermostat skip the event, enter “– –:– –” as the time. The “– – :– –” time is found between 11:50 PM and 12:00 AM.
Away Hold SECTION N To setback the temperature while the occupants are away, use the Permanent Away 2 scene. This scene changes all the devices on the tN4 system to the Away temperature setting. To set the Away temperature, go to the Adjust menu and select the Setpoint (or Hot Tub, DHW, Floor) Away item. When operating a pool, the away scene no longer heats the pool. The Access Level must be set to User, Installer or Advanced. set to the number of days.
the occupied period. During the unoccupied periods, the exchange supply water temperature is lowered by the difference between the occupied and unoccupied setpoints. During the away period, the exchange supply is lowered by the difference between the occupied and the away setpoints. Maximum Supply When the setpoint control is connected to a tN4 system control and the Heat Source item is set to hydronic (HYDr), the setpoint control requests an Exchange Supply water temperature on the tN4 bus.
Outdoor Temperature The setpoint control can display the outdoor temperature in the View menu when connected to a tN4 bus with a device measuring the outdoor temperature. To display the outdoor temperature, set the Out item in the Adjust menu to On. Warm Weather Shut Down The Warm Weather Shut Down (WWSD) feature prevents the setpoint control from heating once the outdoor temperature exceeds the WWSD occupied or WWSD unoccupied setting.
Error Messages Local Errors and Device Errors Error messages are used to indicate a problem somewhere in the system. There are two types of error messages: Local Errors and Device Errors. A Local Error indicates an error specific to a device. For example, a thermostat with a sensor short circuit will show a Sensor Short Error on its display. No other devices will show this specific error (unless they also have a sensor short circuit).
Error Messages (1 of 2) Note: Error Messages are only visible while in the Advanced or Installer access level. Error Message Description ADJUST ERROR The setpoint control failed to read the ADJUST menu settings from memory and has reloaded the factory default settings. Operation stops until the ADJUST menu settings are checked. Note: To clear the error, the access level must be set to Advanced before checking the settings in the ADJUST menu.
Error Messages (2 of 2) Note: Error Messages are only visible while in the Advanced or Installer access level. Error Message Description DEVICE LIMIT There are more than 24 devices on the tN4 bus. The additional devices must be removed and reconnected to a different tN4 bus if possible. DIP SWITCH 2 MODE The tN4 System Control DIP switch 2 is set to None and the thermostat has detected a tN4 System Control. The thermostat does not operate until this error is corrected.
Cleaning the Control The control’s exterior can be cleaned using a damp cloth. Moisten the cloth with water and wring out prior to wiping the control. Do not use solvents or cleaning solutions. Limited Warranty and Product Return Procedure Limited Warranty The liability of tekmar under this warranty is limited.
