6.1 HOW TO SWITCH ON/OFF THE UNIT AND CHANGE CHILLER/HEAT PUMP WORK MODE FROM
VISOTOUCH
Firstly, we will talk about No Motor Condensing Unit. Set Par CF04 = 0.
UNIT SWITCH-ON AND SWITCH-OFF CAN TAKE PLACE:
From the keyboard
From digital input configured as remote ON/OFF
By time bands (see unit switch on/off by RTC)
6.1.1 Unit Switch-ON/OFF From The Visotouch
The unit can be configured as chiller only, heat pump only or as chiller with heat pump mode by par CF02.
For different type of units, the switch ON/OFF procedures are different.
Selection of unit working
1 = chiller only
2 = heat pump only
3 = chiller with heat pump
Note: If user wants change CF02 value, please switch off the unit to “Stand-by” status first. Otherwise, it may
take no effect.
When only the heating is enabled, the ACF1 alarm is not generated if the reverse valves in the envisioned
circuits are not configured.
SWITCH THE UNIT ON/OFF IN COOLING- HEATING MODE FROM THE VISOTOUCH
The configuration should be:
CF04 = 0, (not Motor condensing unit)
CF02 = 3, (chiller with heat pump)
SP09 = 0, (from the keyboard)
In the beginning, the device is in stand-by mode, and the buttons and are all visible. These two
buttons’ position depends on Par SP08.
SP08 = 0: is placed in left, is placed in right.
SP08 = 1: is placed in left, is placed in right.
No matter how to place, the left button is always used for cooling mode. The right button is always used for
heating mode.
Suppose SP08 = 0, press button for 1 second can switch on the unit to work in cooling mode. At this
moment is hidden.
Press the button again, the unit is switch OFF and return to status stand-by. The button and
are all visible now. In this case, user can press button to switch to heating mode or press to restart
the cooling mode.
The device is in stand-by when both and buttons are visible. The stand-by mode is obtained every
time that the unit is off from cooling or heating working mode. Also in stand-by mode, the controller gives the
possibility to:
display the variables detected
manage the alarm situations, displaying and signalling them.
When unit is ON in chiller mode, the status in the screen is “Cool Mode”:
