d05

d05 Time Stagg

Time staggering for defrost cut-ins during start-up

The function is only relevant if you have several refrigeration appliances or groups where you want the defrost to be stag-

gered in relation to one another. The function is furthermore only relevant if you have chosen defrost with interval start

(d03).

The function delays the interval time d03 by the set number of minutes, but it only does it once, and this at the very first

defrost taking place after voltage is connected to the controller. The function will be active after each and every power

failure.

d06

d06 DripOff time

Drip-off time

Here you set the time that is to elapse from a defrost and until the compressor is to start again. (The time when water drips

off the evaporator).

d07

d07 FanStartDel

Delay of fan start after defrost

Here you set the time that is to elapse from compressor start after a defrost and until the fan may start again. (The time

when water is “tied” to the evaporator).

d08

d08 FanStartTemp

Fan start temperature

The fan may also be started a little earlier than mentioned under “Delay of fan start after defrost”, if the defrost sensor S5

registers a lower value than the one set here.

d09

d09 FanDuringDef

Fan cut-in during defrost

This parameter is used to define whether fan is to operate during defrost or not

d10

(1)

d10 DefStopSens.

Defrost sensor

This parameter is to define which sensor has to be used to exit/terminate the defrost.

• (0) 

non

 = none, defrost is based on time set in do4

• (1) 

Air

 = Sair sensor

• (2) 

dEF

 = S5 (defrost) sensor

d18

d18 MaxTherRunT.

Compressor accumulated runtime to start defrost

When the accumulated compressor runtime is equal to the value set in this Parameter, defrost will be triggered. If the com-

pressor runtime is less than the set value during the define defrost interval “d03”, defrost will be triggered based on the

defrost interval “d03”. This feature is disabled when this parameter is set to zero.

d19

d19 Cutout S5Dif

Defrost on demand – S5 temperature

The controller will follow the effectivity of the evaporator, and via internal calculations and measurements of the S5 tem-

perature it will be able to start a defrost when the variation of the S5 temperature becomes larger than required.

Here you set how large a slide of the S5 temperature can be allowed. When the value is passed, a defrost will start.

The function can only be used in 1:1 systems when the evaporating temperature will become lower to ensure that the air

temperature will be maintained. In central systems the function must be disabled. With setting = 20 the function is disa-

bled.

d30

d30 Pd Def Delay

Defrost delay after pull down

This parameter defines the time delay to start the defrost after pull down cycle. This has to ensure defrost doesn’t happen

immediately after pull down cycle.

dA1

--- Def. Start

Defrost start

Parameter used by the network system manager to initiate a scheduled defrost cycle. Only used on Modbus datacommuni-

cation.

dA2

--- HoldAfterDef

Hold after defrost

Parameter used by the network system manager to coordinate the defrost cycle among multiple controllers. Only used on

Modbus datacommunication.

dA3

--- DefrostState

Defrost state

Parameter used by the network system manager to coordinate the defrost cycle among multiple controllers. Only used on

Modbus datacommunication.

This menu can only be set when regulation is stopped, i.e. “r12” is set to 0.

F01

F01 Fan Stop CO

Fan at compressor cut-out

This parameter define the fan operation during compressor OFF cycle.

 = fan follow compressor

• (1) 

Fao

 = fan always ON

• (2) 

FPL

F04

F04 FanStop temp

Fan stop temperature

The function stops the fans in an error situation, so that they will not provide power to the appliance. If the defrost sensor

registers a higher temperature than the one set here, the fans will be stopped. There will be re-start at 2 K below the set-

ting. The function is not active during a defrost or start-up after a defrost. With s50°C the function is disabled.

F07

F07 Fan ON

Fan ON cycle

This parameter is applicable only when the Fan at Compressor cut out “F01” is set to Fan Pulsating mode. The Fan pulsating

ON time will be as per the time set in this parameter.

F08

F08 Fan OFF

Fan OFF cycle

This parameter is applicable only when the Fan at Compressor cut out “F01” is set to Fan Pulsating mode. The Fan pulsating

OFF time will be as per the time set in this parameter.
