1 ntroduction

The Schwank ThermoControl Plus 4M is suitable for the control of single or two-stage /

modulation gas-infrared heating systems.

Depending on the selected operation mode, the controller has 4 to 8 heating zones.

Please read this manual carefully before installing or using the control unit. Failure to follow the

manual and warnings will affect your warranty. They are also a prerequisite for a professional

installation and correct handling.

Please pay special attention to chapter 2 „Safety“.

The ThermoControl Plus 4M is designed to be used for industrial/commercial building heating

systems.

Schwank will not be held responsible for any damages whatsoever resulting from incorrect use.

The controller measures the room temperature and switches the heater on/off by relays.

The controller features different operating programs.

P1…P5: Single-stage, Two-stage and Modulating heaters.

Daytime heating period extension +h

Available as a special feature is the extension of the programmed heating period by a manually

operated button. This button can be installed parallel to the sensor. By pushing the button

(~1 sec.), the value of the programmed daytime temperature in the selected heating zone is

maintained for an additional time period. (Default is 1h, adjustable in the parameter menu)

Programmed temperature values and operating programs

The temperatures and operating programs of every single heating zone are independently

selectable.

- Daytime- , night time- or frost protection temperature , selected by a weekly

schedule

- Continuous daytime ( F X) night time, ( F X) or frost protection temperature ( F X).

- Vacation program: the controller is able to save eight vacation periods, which are programmed

according to the calendar.

Other Features:

– Four air-proving contact inputs

– Four 2-10V modulation outputs

– Illuminated display

– Selectable ºF / ºC temperature display

–

Button for system check mode

–

Real-time clock with calendar, including automatic summmer- / winter time correction

– Outdoor temperature sensor (OAS)

– Heat-up optimization: the heater starts/switches on earlier to ensure that the desired

temperature is achieved exactly at the programmed time.

2 Safety

nstallation details

This is a 24VAC Class 2 extra low

voltage temperature controller. Use

only Class 2 rated power supply. Do

not install on voltages higher than

30VAC.

Read all information in this manual

before installing or programming the

appliance. The electrical installation

and wiring must conform to local and

national building and electrical

standards. Check the electrical

equipment regularly. Defective wires

etc. must be replaced immediately.

Be sure that power routed to the

controller has been powered off

before beginning installation or

making any setting. Make sure that

nobody can connect appliance to the

power supply while you are working.

The Schwank ThermoControl Plus 4M

has to be mounted on/at a place,

where it’s not affected by vibrations

or shocks.

Please install the ThermoControl

Plus 4M ensuring conformity to the

wiring diagram.

Ensure that the controller and the

heater relays are connected by 16

AWG cable and controller and

sensor connected by a 18 AWG

cable.

nstall the room-temperature-

sensor between the radiation

area of two heaters at a height of

2.5 m. Therefore the controller

receives an optimal value of the

nominal temperature.

+If the controller is installed in a large

building or in a building with

extreme temperature differences

(temperature gradiants), you can

also measure average temperature,

connecting additional room-

temperature sensors for every

single heating zone control circuit.
