    Program for one outlet tot use a Teco TK 1000 chiller

    Hi all,
    I,am using a Teco TK1000 chiller witch also is a heater. Is it posible to control it on one outlet, as wel for chilling and heating? The TK 1000 has its own t-stat.

    Will the code on the sticky topic do the trick?

    The following code will keep your tank temperature between 79 and 80 year round.

    [Chiller]

    Fallback ON
    If Temp > 80.0 Then ON
    If Temp < 79.5 Then OFF

    [Heater]

    Fallback ON
    If Temp < 79.0 Then ON
    If Temp > 79.5 Then OFF
    If Temp < 70.0 Then OFF <-- this is in case the temp probe fails and gives you a false reading

    Here's a way to visualize the integrated Heater and Chiller program above:


    79.0 79.5 80.0
    | | |
    |------- HEAT -----------------|------- CHILL ---------------|
    0N OFF ON


    The heater will turn on at 79 (actually 78.9) and heat until the water rises to 79.5 (actually 79.6) then turn off.
    The chiller will turn on at 80 (actually 80.1) and cool until the water cools to 79.5 (actually 79.4) then turn off.

    If you have a heater with its own t-stat, you would set that t-stat to maintain a temp just slightly warmer than 79.5.
    If you have a chiller with its own t-stat, you would set that t-stat to maintain a temp just slightly cooler than 79.5.

    This way even if the Apex fails to turn off the heater or chiller, their own internal t-stat will turn them off. And by setting their t-stat to just slightly warmer/cooler than 79.5, you're insured they will always turn ON when the controller wants them to be ON.


    Thx in advance

    With that kind of unit, I would use the apex as a backup like this

    Fallback ON
    Set ON
    If Temp > 80.9 Then OFF
    If Temp < 78.1 Then OFF
    Min Time 030:00 Then OFF
