1 Introduction
The Schwank ThermoControl Plus 4 is suitable for single or two-stage gas-infrared heating
systems.
Dependant upon its operation the controller has one or two controller circuits.
Please read this manual carefully before installing or using the control-unit. Failure to follow the
notes and warnings will affect your guarantees. They are also a prerequisite for a professional
installation and correct handling.
Please pay special attention to chapter 2 “Safety“.
The ThermoControl Plus 4 is designed to be used for industrial/commercial building infrared
heating systems only. Other or further uses are not suitable.
Schwank will not be held responsible for any damages whatsoever resulting from incorrect use.
The controller measures the radiant and ambient temperatures in the space and switches the
heater(s) on/off by relays.
The controller features different operating programs.
-P1…P5: single- or two-stage controller for luminous gas-infrared heaters and tube heaters
Override day temperature mode +h
Available as a special optional feature is a setback override bu tton that manually extends the
programmed heating period. This bu tton is installed parallel to th e sensor. By pushing the button
(~1 sec.), the nominal value of the programmed temperature in t he selected control circuit is
maintained for an additional programmable time period. (Default 1h)
Programmed temperature values and operating programs
The temperatures and operating programs of each single control circuit are independently
selectable.
- Day- , night- or anti-freezing temperature , selected by a week program
- Continuous day-( FIX) night-( FIX) or anti freezing temperature ( FIX).
- Holiday program: the controller is able to save eight holiday periods, which are programmed
according to the calendar.
Other Tools/Features:
– Illuminated display
– Selectable ºF / ºC temperature display
– Button for service maintenance operation mode
– Real-time clock with calendar, including automatic summer / winter time correction
– Outdoor temperature sensor (SA)
– ‘Smart’ adaptive recovery: based on outdoor temperature, adjusts system ramp-up to ensure the
desired occupied temperature is achieved at the programmed time.
– Remote controlled day-mode operation
– ‘On’ cycle record at each output
– Error-relay: relay switches on in any case of error

2 Safety
This is a 24VAC Class 2 low voltage
(24Vac) 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. Electrical installation and
wiring must conform to local and
national building and electrical
codes. Check the electrical
equipment regularly. Defective wire
etc. must be replaced immediately.
Be sure that power routed to the
controller has been powered ‘off’
before beginning installation or
installation of communication
modules. Lock out the power supply.
The Schwank ThermoControl Plus 4
must be mounted where it is not
affected by vibration or shock.
The feed/supply line must be
protected by the installer with a fuse
of maximum 16 A.
Install the ThermoControl Plus 4
ensuring conformity to the wiring
diagram located in the switchboard.
Minimum Wiring Connection:
It is the installer’s responsibility
to ensure that wire gauge is
sufficient to provide 24Vac from
the transformer to the controller,
and from the controller 24Vac
outputs to the external relays
that power heaters and exhaust
fans. The distance between the
power source and equipment
must be considered.
24Vac power from 100VA
transformer to the controller
with minimum 16 AWG wire
24Vac from controller outputs
to equipment power relays
with minimum 16 AWG wire
Connect sensor to controller
with minimum 18 AWG wire
Install the IR temperature sensor
between the radiant area of two
heaters at a height of 6 ft (2 m)
above floor. In this location the
controller receives the optimal
value of the comfort temperature
(radiant temperature plus
ambient temperature).
NOTE: If heating zones are dimensionally
large in size or there are extreme
temperature gradiants within the
zone, temperature averaging can
be achieved using four IR sensors
wired in parallel-series for each
zone.
