c11 | Delayed compressor delay |
| Not used by Foster |
| Default: c11 = 4 |
d0 | Type of Defrost |
| Sets the type of defrost required. |
| Default: d0 = 0. Foster setting d0 = 1. Hot gas defrost terminated by evaporator probe or in the event of |
| probe failure by time (see dP1). |
dI | Interval between defrosts. |
| The defrosts are performed periodically at an interval equal to the value of ‘dI’ in hours. |
| The interval is cyclical and is maintained if the controller is turned OFF, when the controller is turned back |
| ON a defrost will occur if the interval was exceeded. |
| Default: dI = 8. Foster setting dI = 6. |
dt1 | End defrost temperature, evaporator probe. |
| The evaporator probe termination temperature, in the event of a probe failure the defrost will be terminated |
| by time (see dP1). |
| Default dt1 = 4.0. Foster setting dt1 = 20.0. |
dt2 | End defrost temperature, auxiliary evaporator. |
| Not used by Foster. |
| Default: dt2 = 4.0. |
dP1 | Maximum defrost duration, Evaporator. |
| Maximum time, in minutes, for defrost in the event of evaporator probe failure. |
| Default: dP1 = 30. Foster setting dP1 = 20. |
dP2 | Maximum defrost duration, auxiliary evaporator. |
| Not used by Foster |
| Default: dP2 = 30. |
d3 | Defrost start delay |
| Not used by Foster. |
| Default: d3 = 0. |
d4 | Enable defrost at start up. |
| Activates a defrost when the defrost is switched on. |
| 0 = no defrost performed when the instrument is switched on |
| Default: d4 = 0. |
d5 | Defrost delay at start up. |
| Not used by Foster. |
| Default: d5 = 0. |
d6 | Display during defrost. |
| 1 = The last temperature read prior to the start of the defrost remains on the display. The display returns to |
displaying the temperature when the set point is achieved. Default: d6 = 1.
ddDripping time after defrost.
The time, in minutes, that the evaporator fans are delayed after defrost to allow for the evaporator to drip. Default: d6 = 2. Foster setting d6 = 1.
d8 Bypass alarms after defrost.
The time, in hours, that the high temperature alarms is disabled for after the end of the defrost cycle Default: d8 = 1.
d9 Defrost priority over compressor protection. Not used by Foster
Default: d9 = 0
