3.6 SETTING OF THE WATER PARAMETERS
The operations described in this paragraph are only necessary if the ACF is not
connected to a Direct Digital Controller (DDC). If the ACF is connected to a DDC,
refer to the manual provided with the DDC.
This paragraph describes the hydraulic parameter settings on the S61 circuit board
of the ACF. If you are not familiar with basic usage procedures of the circuit board,
refer to paragraph 2.2 ON-BOARD ELECTRONICS on page 30.
Go to menu 3 of the circuit board to configure the ACF.
There are three parameters that can be set for the hydraulic configuration; select the letter
E to return to the previous menu.

Table 23 – ACF hydraulic configuration parameters, set from menu 3.
Parameter descriptions:
Selection of water delivery/return thermostat, parameter 73: this parameter can be either 0
or 1.
•
0: the temperature that controls ignition/shutdown of the ACF is detected
by the ACF’s RETURN water sensor.
•
1: the temperature that controls ignition/shutdown of the ACF is detected
by the ACF’s DELIVERY water sensor.
Water set-point, parameter 75: this parameter sets the water temperature at which the
ACF turns off.
Water differential, parameter 76: this parameter is the number of degrees added to the
set-point which determines the ignition temperature of the ACF.
The ACF will chill the water until the Set-Point temperature is reached. At this point it will
turn off. The water temperature will rise to the Set-Point + Differential temperature; when
reached, the ACF will turn on.
Example:
Water delivery/return thermostat: reading from water delivery sensor.
Set-Point: +7.0°C
Differential: 2.0°C
