MC19-1.20

 For a Step segment Holdback delays continuation to the next segment until the step

target is reached.

The Holdback Type can be set as follows:

 Low Applies to heating only

 High Applies to cooling only

 Band Applies to both heating and cooling

 Off Holdback is off

To set the Holdback type press page  twice, then press scroll  until the display shows

Holdback Type for each segment and press up  or down  to set.

The default setting for Holdback is Off.

5.3 Wait Segments

Wait prevents the program proceeding to the next segment, in a similar way to Holdback,

until the selected ‘Wait-For’ parameter has been met. There are 5 ‘Wait For’ parameters.

The first 4 only work if there are configured inputs to the controller.

1 PrgIn1 Wait until Input 1 is true

2 PrgIn2 Wait until Input 2 is true

3 PrgIn 1&2 Wait until Inputs 1 AND 2 are true

4 PrgIn 1or2 Wait until Inputs 1 OR 2 is true

5 PVWaitIP Wait until the measured temperature reaches a threshold value before

continuing. It can operate in one of 4 ways:

5.1 ‘Abs Hi’ Wait until the measured temperature is greater than or equal to a

value ‘WaitVal’ set for that segment.

5.2 ’Abs Lo’ Wait until the measured temperature is less than or equal to a value

‘WaitVal’ set for that segment.

5.3 ‘Dev Hi’ Wait until the measured temperature exceeds a fixed* threshold by

an amount ‘WaitVal’ set for that segment.

5.4 ‘Dev Lo’ Wait until the measured temperature drops below a fixed* threshold

by an amount ‘WaitVal’ set for that segment.

* The fixed threshold used by deviation parameters is set in the configuration level of the

programmer and if required should be requested when purchasing a furnace from Carbolite.

5.4 Program Cycling

The Cycles parameter sets the number of times the program will run.

The default setting is 1 cycle.

shows Prog Cycles, then press up to set a finite number of cycles up to 999. Or press

down to set cycling to continuous.

5.5 Creating a Program

From the home display, press page  three times to get to the programming page, the

display will show “ProgEdit  1”.
