Use of control panel.
Introduction
This section describes how to use the control panel on the front of the unit. The panel's
functions vary depending on whether accessories have been mounted or not.
On the front of the unit you will find brief instructions under the front cover.
Summer cooling
mode
In summer mode the supply fan stops and the addition of fresh air comes from open
doors and windows.

Press and hold for 5 seconds to enable or disable
summer cooling
mode
.

The supply fan does not run in summer mode .

Cooler, fresh air is brought in from an open window, e.g.
The exhaust fan will continue to run, thereby generating air cir-
culation.

Summer mode can only be enabled if the outside air (T1) is above 14°C
When summer mode is enabled, the LED light will light for 5 seconds at a time, inter-
rupted by 1 second intervals.
Automatic cooling
via bypass Automatic bypass cooling is only possible if the bypass module is installed and enabled.
It is possible to set the parameters for bypass cooling. The following options are availa-
ble on HRC3 remote controller and Dantherm PC-tool:
 Set the minimum outside temperature within the range 8-15°C.

Set the bypass setpoint, which makes the bypass damper open. Range: 22-
30°C. You can select "off" to disable automatic bypass
This is called Tmax.
The following preconditions will enable automatic bypass cooling:

If the outside temperature is 2°C lower than the indoor temperature

AND Tmin is higher than the setpoint (between 12-15°C).
 AND Tmax is higher than the setpoint (between 21-27°C).
The bypass damper will close if one of the three preconditions listed above deviates by
2°C
The bypass LED will light constantly when the bypass damper is open.
Continued overleaf
If the by-pass temperature settings are set too low,
there is a risk that the unit will open by-pass while
the central heating system in the house is active.
