7 REGULATORS
7.1 Initial information
The CF06 parameter makes it possible to configure the meaning of the sun and snowflake LEDs according to the following coding.
- CF06 = 0
- CF06 = 1
= heating / = cooling
= heating / = cooling
7.2 Function mode
The following function modes are available
- Parameter CF13 enables the Heating function
- Parameter CF14 enables the Cooling function
If neither mode is enabled, the unit will in Cooling mode.
The function mode can be selected on the keypad: to move from one mode to another, simply press the On/Standby key.
7.3 Compressor
The adjustment is based on the value provided by the input water probe. The compressor is run on the basis of this temperature and of
the set-point.
If a modulating compressor is to be used, connect it to analogue output AN1, in which case it will be adjusted by a proportional-integra l
controller (PI). Output DO4 provides the enable signal to the modulating compressor DO4. In order for the enable signal to be
synchronised with the compressor control signal, parameter CP08 must be other than 0.
Parameter CP01 determines the minimum time between the compressor switch-off and its successive switch-on, while parameter CP02
determines the minimum time between two successive switch-ons (that is to say the maximum number of switch-ons per hour).
Parameters CP05 and CP06 have a different meaning depending on the type of analogue output, selected by parameter CF35: if the
output is a frequency, they represent the maximum and minimum working frequencies, otherwise they represent the maximum and
minimum working percentages.
If ON-OFF type compressors are to be used, parameter CP08 must be set at 0. Compressor is connected to output DO4.

7.3.1 Adjustment in cold mode
The regulators can work in cold (chiller) mode if parameter CF14 is configured correctly.
The diagram below represents the proportional adjustment in cold mode. To keep it simple, the integral component is not represented
(Rl04 = 0). The compressor enable outlet is also shown.
For ON-OFF adjustment, the cut-off delta must be set to 0 and there will be only one adjustment step, as shown on the diagram below.

EVCO S.p.A. EV3 HP & EVD HP | Installer manual ver. 1.2 | Code 1443DHPE124
7.3.2 Adjustment in hot mode
The regulators can work in hot (he at pump) mode if parameter CF13 is configured correctly.
The diagram below represents the proportional adjustment in hot mode. The integral component is not represented (Rl04 = 0).
For ON-OFF adjustment, the cut-off delta must be set to 0 and there will be only one adjustment step, as shown on the diagram below.
7.3.3 Oil refresh
If the compressor is running at a frequency lower that the CP09 parameter for a period longer than the CP10 parameter, it is activated
at the maximum frequency. The compressor will remain at the maximum power until it reaches the set-point.

7.4 Hydraulic pump
7.4.1 Initial information
The functional mode of the hydraulic pump can be set using parameter Pm03: the pump may be always kept switched on or be
switched on for thermoregulation in relation to the functioning of the compressor.
In the second case, the pump switches off after a delay of PM02 from when the compressor is switched off every time it is deactivated
by the regulator. It will switch off immediately if an alarm sounds requiring the pump to be stopped, as for the flow alarm in manual re-
arm (with the flow alarm active in automatic re-arm, the pump stays switched on).
7.4.2 Function modes
The hydraulic pump can be set to function in two modes.
Continuous The pump is always in ON mode if PM03 = 0
On-call The pump is switched on at the request of the heat regulator if PM03 = 1. The compressor is activated with a delay (PM01)
from pump switch-on and the pump is switched off with a de lay (PM02) from when the compressor is switched off, as
shown below:
7.4.3 Antifreeze function
When the temperature of the input or output water is below PM04, the pump is activated automatically if it was switched off. The pump
switches off when the temperature rises abovethe value of the antifreeze threshold, to which must be added the hysteresis (PM05).

7.5 Electric heating elements
7.5.1 Initial information
The digital output that controls the electric heating elements may also be used for enabling a boiler.
7.5.2 Heating elements in integration mode
The heating element output in integration mode is only activated if the system is in Heating mode.
The heating elements come on when the temperature of the adjustment probe falls below threshold set by parameter HEAt - Fr12 for a
time period of Fr11. They switch off when the temperature rises above the threshold set by (HEAt - Fr12) + Fr05. If the compressor is
in alarm mode, the adjustment is made without delay from when the heat set-point is reached.
7.5.3 Heating elements in antifreeze mode
The heating element comes on when the pump is switched on and the minimum temperature between the input and output water is
lower than the parameter Fr02.

7.6 Condensation control
7.6.1 Initial information
The condensation is controlled by adjustments to the fan that can either be a proportional or O N-OFF type.
If an ON-OFF fan is to be used, connect it to digital output “Enable fan”.
If a proportional adjustment fan is to be used, it should be connected to analogue outlet “Fan”. If an enable outlet is to be used to work
the modulating fan it only has to be connected to digital output “Enable fan”.
For modulating fans, parameter Fn01 enables the start-up time only if the output is configured as cutting phase (CF36 = 1.
The fan can be adjusted independently of the compressor (Fn03=1) or at the request of the compressor (Fn03=0). When the fan is
switched off this will be by-passed by a time equal to Fn06 from switch-on of a compressor. During this period, the fan is set to
minimum speed if the regulator requests cut-off.
7.6.2 Adjustment in cold mode
The diagram below represents the proportional adjustment in cold mode.
In this mode, parameter Fn13 (external fan pre-ventilation time) is also activated to avoid the compressor starting up at a
condensation temperature that is too high. Depending on this parameter, the fan is activated for a time equal to Fn13 before the
compressor is switched on and the fan speed is proportional to the condensation temperature. During this period, the fan is set to
minimum speed if the regulator requests cut-off.
The diagram below represents the ON-OFF adjustment in cold mode.

7.6.3 Adjustment in hot mode
The diagram below represents the proportional adjustment in hot mode.
The diagram below represents the ON-OFF adjustment in hot mode.
7.6.4 Regolazione in sbrinamento
During the start-defrost period, the fan remains off.
The diagram below represents the fan adjustment when a defrost cycle is underway (with compressor in On mode).
During the dripping period, the fan is first switched off and once the 4-ways valve is inverted, it is switched back on at the maximum
speed for a time equal to dF07.

EVCO S.p.A. EV3 HP & EVD HP | Installer manual ver. 1.2 | Code 1443DHPE124
7.7 Defrost
7.7.1 Initial information
The defrost function is only active if the system is in Heating mode and enabled by parameter dF01.
dF01 = 0 Defrost disabled
dF01 = 1 Defrost with activated compressor
dF01 = 2 Defrost for compressor stop (similar to dF01 = 1 but without activating the compressor)
dF01 = 3 Time interval defrost (similar to dF01 = 1 but ending up for exceeded time)
The battery probe regulates the start and end defrost cycles.
7.7.2 Start defrost control
When the reading indicated by the probe is below the dF02 threshold and the compressor is activated, a counter starts up. When the
counter reaches the dF03 value and the dF08 time period has elapsed since the last defrost, a defrost cycle is activated. The counter
stops if the probe reading rises above the dF02 threshold or the compressor is switched off.
The reversing valve is regulated after a delay equal to the time expressed by parameter dF06 and the compressor is switched back on
at full power (df01 = 1 o 3) after a further wait equal to the time expressed by the parameter dF06, also with a switch-on waiting time
of dF09. If the reading rises above Fn20, the fans are activated on full power; if it falls below Fn20-Fn21, the fans stop.
The diagram below shows the start defrost cycle.
7.7.3 End defrost control
Defrost is interrupted when the reading detected by the probe rises above the dF04 threshold (df01 = 1 o 2) or if the duration of the
defrost is equal to Df05 (always valid if df01 = 3)..
Just as for the start defrost control, the reversing valve is regulated after a delay equal to the time expressed by parameter dF07 and
the compressor is switched back on at full power after a further wait equal to the time expressed by parameter dF07.
The diagram below shows the end defrost cycle.
