Building Technologies General and central functions 2013-06-17
11.11 Test mode (Test, 7)
The following override functions are used to commission the controller and for service
purposes, e.g. to test a valve actuator.
The controller must first be switched to HVAC test mode by transmitting the value
7=TEST via Application mode.
To quit test mode, first transmit 6=OFF, and then 0=AUTO.
In test mode, the valves, air dampers, electric heating coils and fans can be set to
defined values via KNX bus signals.
A soft reset is carried out when the controller exits from Test mode:
– Motorized valve actuators and dampers are synchronized.
– Thermal valves are preheated (see page 86).
– The control algorithm but not the complete application is restarted.
Test mode is possible only with S-mode objects!
11.12 Emergency heating (Emergency Heat, 8)
This function is used for emergency heating when the room temperature or return air
temperature drops below the frost protection setpoint. The function is independent of
the effective room operating mode.
It affects the control of all installed heating equipment.
When using a radiator and a heated ceiling the valve opens 100 %.
An electric radiator is switched to the highest stage and remains there until the
temperature rises above the Protection heating setpoint again.
When the room temperature rises above the Protection setpoint, the controller reverts
to the original room operation mode (see 145).

Emergency Heat
The following condition must be fulfilled:
– The building temperature must be below the Frost setpoint.
The function can NOT be disabled in the room controller by means of the tools.
The function must be enabled via the building automation and control system
(communication object Application mode, see page 145).
