Scope of delivery
General
Systems with mixed heating circuit are controlled via the heating circuit controller.
Required heating circuit temperature is determined in the flow, depending on
outside temperature.
Systems with heat source and hot water tank are controlled via the differential
temperature controller (differential sensor not included in delivery). When the heat
source temperature exceeds the tank temperature by the value set on the
controller, the circulation pump is activated by the control and the heat absorbed
in the heat source is transported to the hot water tank.
Intended use
The unit is manufactured in accordance with state of the art technology and
approved safety regulations. Nevertheless, using the unit can cause danger to the
user or third persons, or damage to the unit and other assets. The unit must be
used exclusively as heating circuit controller or differential temperature controller.
Safety
All electrical connections, safety measures and protections have to be carried out
by an authorised professional electrician according to the valid standards and VDE-
guidelines, as well as the local regulations. The electrical connection must be a
fixed connection according to VDE 0100.

4. Functions with direct access
Manual operation
— Activate by pressing and holding button
— end function by pressing button
Adjustment room setpoint
Press buttons and in the basic display to directly set room day
temperature. Such a variation changes the parameter 06:02 (see parameter
description).
+ Controller is in manual mode
Function: Manual operation allows manual start-up of the heating circuit or
measurement of emission without automatic functions. Manual
operation has no influence on an activated Delta-T control.
— The heating circuit pump runs continuously
— The mixing valve is de-energised
Important!
This function shall only be used by an authorised professional.
Heating circuit temperatures are not monitored during
measurement of emission. Faulty operation or unsupervised
operation of this function may result in damages to the heating
system.
