  • TP-89 digital bus thermostat 1 / 2 MKL51701
    The TP-89 digital bus thermostat
    The TP-89 is an indoor thermostat which can be used to set and
    measure the temperature in a room. The thermostat is designed to
    work exclusively in combination with AC-8007 / AC-8014 / AC-814
    receivers. Temperature adjustment can be performed simply by turning
    the setting knob. This knob can be locked to avoid accidental setting.
    The thermostat does not use any programmed scheduling. The
    following features are also available:
    Anti-freeze protection – any drop in temperature under the
    (configurable) AL Lo value is detected and signalled to the
    receiver, causing the receiver’s FRE output terminal to be activated.
    Floor temperature detection – the thermostat is equipped with an
    input terminal for the connection of a temperature sensor such as
    the TS-80. This is especially suitable for under-floor heating control
    – by placing the sensor directly into the floor heating regulation can
    be performed with higher precision. As a result, using the TP-89
    and the TS-80 in combination allows for a comfortable floor
    temperature with no additional risk of damaging the floor.
    Installation and enrollment
    The TP-89 should be mounted in a dry indoor location. Choose a
    mounting location about 1.5 meters above the floor in an area with
    good air circulation. Avoid places with draughts, dead air spots and
    radiant heat from the sun or appliances.
    1. Release the upper cover by pressing the plastic tab on the bottom
    side of the housing
    2. Mount the back part on to the desired location.
    3. Connect the receiver’s digital bus jumper to the BUS terminals.
    The polarity is irrelevant.
    4. Should a floor sensor be used, wire it to the SEN terminals.
    5. Close the thermostat.
    6. Enroll the thermostat to the receiver by pressing and holding the
    knob for 5 seconds. The receiver must be in enrollment mode (see
    the AC-8007/8014/814 manual).
    Configuring the fixed parameters
    The thermostat works with the following temperature thresholds:
    t Lo (economic), t Hi (comfort), AL Lo (fault/freeze), FL Lo (floor low
    temperature) and FL Hi (floor high temperature). Each of the
    parameters is configurable within a corresponding temperature range –
    see the table below.
    You can enter the adjustment menu by keeping the knob pressed for
    10 seconds. Scrolling the menu is done by turning the knob. The
    display will show temperature parameter names – see the table below.
    The currently displayed parameter can be adjusted by pressing the
    knob briefly, turning the knob until the desired temperature is
    displayed, and confirming the setting by re-pressing the knob (this will
    also cause a return to the menu so that you can configure other
    parameters immediately). The adjustment menu is escaped from by
    pressing the knob while OK is displayed or automatically after 30
    seconds. The parameter ranges are restricted according to the table.

    Temperature accuracy adjustment: The thermostat allows you to
    configure the hysteresis – the accuracy to which the temperature is
    regulated. The setting is done via the SPAN item in the adjustment
    menu (proceed the same way as with the threshold parameters
    mentioned above). Turning the knob lets you select one of the
    following accuracy ranges: ±0.1˚C, ±0.2˚C or ±0.5˚C (the factory
    default setting is ±0.2˚C).
    Example: If the accuracy is adjusted to ±0.5˚C and the temperature is
    set to 24˚C, the thermostat switches the heating on when the
    temperature drops below 23.5˚C and it switches it off if the
    temperature goes above 24.5˚C. In reality the temperature scatter can
    be slightly higher because of the temperature persistence of the room.
    Warning: too high an accuracy can cause the heating to turn on
    and off too frequently.
    Temperature measurement correction: Possible temperature
    measurement offsets can be corrected via the Corr item in the
    adjustment menu. The range of adjustable corrections is ±1°C.
    Manual operation
    When not being handled, the thermostat shows the current
    temperature in the room.
    By turning the knob the desired temperature can be set from t Lo
    to t Hi (during setting, a hand symbol is shown on the display). If
    the temperature cannot be set, see “Locking the thermostat”.
    Setting the t Lo and t Hi limits allows the installer to prevent the
    regulated temperature from being set to undesirably high or low
    values by manual operation.
    Example: If t Lo = +15°C and t Hi = +22°C then the regulation
    temperature can only be set within the range of +15 to +22°C
    (unless the adjustment menu is entered).
    If you stop turning the knob the current temperature in the room will
    be displayed again (3 seconds after the last movement of the
    If the current temperature is lower than the desired
    temperature minus the hysteresis, the thermostat will switch the
    heating on (a symbol of wavy lines will appear on the display).
    If the current temperature is higher than the desired
    temperature plus the hysteresis, the thermostat will switch the
    heating off (the symbol of wavy lines will disappear).
    Floor heat detection
    If enabled by setting FL On, floor temperature detection is performed
    using a sensor located in the floor. The FL Lo and FL Hi parameters
    allow you to set temperature thresholds for under-floor heating
    If the current floor temperature is lower than FL Lo, the
    thermostat will switch the heating on. This way a comfortable floor-
    temperature is maintained even if no switch-on request is
    generated due to the room temperature.
    If the current floor temperature is higher than FL Hi, the
    thermostat will switch the heating off. This prevents the floor from
    being damaged by too high a temperature.
