  • Page 20: Sequence Of Operation

    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. The sensor is required to be located at the temperature control point. The setpoint control can have an occupied temperature setting.

  • Page 21: Mode 3 - Dhw Tank

    Mode of Operation The hot tub mode of operation can be set to either Heat or Off. While set to Off, Relay 1 remains off. The Off setting should only be used when the hot tub is drained or when there is no possibility of freezing. Power should never be removed from the setpoint control as this will result in an error message on the tN4 system.

  • Page 22: Mode 4 - Floor

    Application Mode 4 - Floor SECTION D Application Mode 4 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.

  • Page 23: Remote Enable / Disable

    Remote Enable / Disable SECTION E To use the Remote Enable / Disable feature, the setpoint control must be set to Mode 1 (Setpoint), 2 (Hot Tub), or 4 (Floor). When the setpoint control is connected to a tN4 system, a User Switch or tN4 Gateway can remotely signal a setpoint control (or multiple setpoint controls) to override the unoccupied temperature to temporarily operate at the occupied temperature.

  • Page 24: Sensor Input

    SECTION F The Setpoint Control 161 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.

  • Page 25: Scenes

    Scenes SECTION H Scenes are a system override feature available when the setpoint control is part of a tN4 system. Scenes allow the user to change the entire tN4 system to operate at preset temperatures. To use the scene function, go to the Scene menu and set the Scene setting to On. The tN4 scene can be changed through the scene menu on a tN4 thermostat, a tN4 User Switch or through a tN4 Gateway.

  • Page 27 Relay 1 System Pump In order to accommodate many different piping and pumping configurations, the setpoint control is able to choose whether a “system” pump is required to operate at the same time as Relay 1. This allows each manifold on a water temperature to have a “system”...
  • Page 28 When the setpoint control is connected to a tN4 boiler bus, the address range is b:01 through to b:24. When the setpoint control is connected to the tN4 mix 1 bus, the address range is 1:01 through to 1:24. When the setpoint control is connected to the tN4 mix 2 bus, the address range is 2:01 through to 2:24.

  • Page 29: Error Messages

    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.
  • Page 30 If the error message is a Device Error (if “DEV” or “DEV ERR” is shown on screen), read the address shown and go to the device with that address. That device will have a Local Error indicating specifically what the problem is. When the problem is corrected, the error message will automatically clear.
