2. Safety
Safety instructions
The following safety instructions make no claim to completeness. If you have any questions, uncertainties or
problems, please contact your contract partner.
Qualified personnel
Only qualified personnel may carry out work such as transport, mounting, installation, commissioning, service
and maintenance. National and company accident prevention regulations must be strictly observed.
Documentation
Before installing and commissioning, please read this documentation and any other documentation to which
reference is made in its entirety. Incorrect handling can lead to personal injury or damage to property. It is
essential that you comply with the technical data, connection details and ambient conditions.
Safety requirements
Check the electrical equipment regularly.
When working on the electrical equipment, the device must be disconnected from the power supply.
Secure the device against unintentional restarting. Switching off at the main switch does not mean
that the control is de-energised.
Setting and changing the function parameters may only be carried out by Schwank service
technicians.
Intended use
The SchwankControl control is exclusively intended for the control of hall heating systems from Schwank. Any
other use or use going beyond this is considered improper use. Schwank GmbH accepts no liability for any
resulting damage. Risk through improper use is borne solely by the user.

Network and buses
For setting up larger heating systems, up to eight control units with a maximum of two operating units can be
connected via CAN bus. Each operating unit allows independent operation of all control units located on the
bus.
CAN 2.0B standard baud rate 125 kBit
The control unit is equipped with two RS485 interfaces for networking Schwank automatic burner control units
and for integrating the SchwankControl into building control systems.
The operating unit can also be connected to a LAN. The operating unit can be operated via a web interface
using other computers in the network.
Ethernet 10/100 Mbit

The three-way valve in hybrid systems can also be
tested in this way.

Revision: 3.0 Page 12 of 71
Figure 8: Temperature and humidity
In addition to the operating mode, select the desired time program for the zone. This program is only used in
automatic mode.
When using automatic mode, a time program must be assigned in advance. To do this, select the "No time
program assigned" field and create a separate time program. The creation of time programs is described in
section 5.4.1.
All programmed holiday periods apply to the entire control unit, but to only those zones in automatic mode
that take holiday periods into account. Setting holiday periods is described in section 5.4.2.
5.3.2. Temperature and humidity setpoints
The setpoints for temperature and humidity
can be edited by selecting the colour-
highlighted pencil. The following screen
appears:
If the measured humidity is higher than the pre-set value, the heating request remains active, even after the
setpoint temperature has been reached, to reduce the humidity / until the setpoint value has been reached.
It is also possible to switch off the humidity control.
The manual mode setting is given in percent and refers to the output value of the control output.

You can set and edit times under the Settings menu item on the Home screen [section 5.1].
5.4.1. Time program
The ON time period is set within the time program. Outside of this period, operation changes to the OFF state.
Programming is only carried out for automatic mode and each zone must be assigned separately in the Zone
details menu item [section 5.3]. Each time program can be activated / deactivated separately.
Up to 4-day heating phases can be set within each time program.

5.4.2. Holiday periods
The holiday periods set here are taken into account in “Automatic mode including holidays” [section 5.3.1].
During this time, the selected zone is heated to the previously determined holiday temperature. A total of up
to 6 different holiday periods can be set.

5.6. Special functions
5.6.1. Heating time extension
Function:
The day temperature is activated for the parameterised time period.
Premise:
The overtime button for the corresponding zone must be installed.
Execution:
By pressing the overtime button for at least three seconds, the setpoint changes to day temperature for the
time period defined by the parameters, regardless of the current operating mode of the zone. As soon as this
time has elapsed, the zone automatically returns to the previous operating mode. The activated heating time
extension is displayed in the info bar [section 5.3.3].
A permanent actuation of the overtime button causes a sensor fault, which prevents further control. This results
in full load heating.
