Auto Mode Setting; Temp. Type Setting (To Activate The Internal Temperature Probe Of The Controller As Room Thermostat) - Ferroli OMNIA H Series Installation, Maintenance And User Manual

AUTO mode setting

Controlling AUTO mode typically consists of the following:
1. T4AUTOCMIN:setting the minimum operating outdoor air temperature for cooling
2. T4AUTOHMAX: setting the maximum operating outdoor air temperature for heating
To determine whether the AUTO mode is effective, go to MENU> FOR SERVICEMAN>
AUTO MODE SETTING. Press OK. The following page is displayed.
Use ◄ ► and ▼ ▲ to scroll and adjust the parameter.
T4AUTOCMIN is the minimum operating outdoor air temperature for cooling in auto mode. The unit will turn off if the outdoor air
temperature is lower when in space cooling operation.
T4AUTOHMAX is the maximum operating outdoor air temperature for heating in auto mode. The unit will turn off if the outdoor air
temperature is higher when in space heating operation.
The relationship between heat pump operation and outdoor air temperature is described in the picture below
In the picture, AHS is an additional heating source. IBH is a backup heater in the unit.

Temp. Type setting (to activate the internal temperature probe of the controller as room thermostat)

NOTE
Through this submenu, you can defi ne whether the unit will operate according to water setpoint sent to the system and
/ or based on the room temperature setpoint.
The TEMP. TYPE SETTING is used for selecting whether the water fl ow temperature or room temperature to control the heat pump
is ON/OFF. When ROOM TEMP. is enabled, the target outlet water temperature will be calculated from climate-related curves.
To enter the TEMP.TYPE SETTING, go to MENU> FOR SERVICEMAN> TEMP. TYPE
SETTING. Press OK. The following page is displayed:
If you set WATER FLOW TEMP. to YES, and set ROOM TEMP. to NON, the water fl ow
temperature will be displayed on the home page, and the water fl ow temperature will work
as the target temperature.
If you set WATER FLOW TEMP. to YES, and set ROOM TEMP. to YES, then the water
temperature will be displayed on the home page. Both water temperature and room tem-
perature will be detected and when either the water temperature or the room temperature
reaches the target temperature the unit will turn off.
In this state, the fi rst target outlet water temperature can be set in the main page, the
second one can be calculated from the climate-related curves. In heat mode, the higher
one will be the real target outlet temperature, while in cool mode, the lower one will be
selected.
