The fan control behaviour depends on the selected operating mode on the control
panel.
In position "A" the fan speed 3 is continuously activated.
–
In positions "1" to "5" the fan is deactivated as soon as the setpoint tempera-
–
ture is reached. Deactivation is performed by taking into account the minimum
running time (2 min.) and repeated activation following minimum downtime (1
min.).
Depending on the selected controller, the integrated valve controller supports
open/close and modulating valves.
The valves can be controlled in the following modes:
Heating
–
Cooling
–
Cooling or heating
–
Heating and cooling
–
In order to reach a common starting position, the factory set synchronisation
mechanism moves all connected valves (only modulating valves) to OPEN or
CLOSE position every 12 hours.
The condensate pump drains the condensate that forms on cooling units.
Depending on requirements, the condensate pump is activated by a float switch.
When a limit value is exceeded, the fan is switched off, the cooling valve is closed
and an error message is displayed on the control panel.
Standby mode is only available with room temperature control option. This does
not regulate the temperature to a fixed setpoint, but instead to a pre-set setpoint
range. The DencoHappel MATRIX.PC service software enables to change this
setpoint.
The standby mode is activated if a room temperature sensor is connected but no
room temperature setpoint, i.e. no control panel, is available (e.g. during con-
struction phase and drying of building).
The "standby mode" function is terminated as soon as the fixed room temperature
setpoint is set.
