Caution! Read and understand the instruction before us-
ing the product.
Caution! Ensure that the installation complies with local
safety regulations.
Warning! Before installation or maintenance, the power
supply must first be disconnected in order to prevent po-
tentially lethal electric shocks! Installation or maintenance
of this unit should only be carried out by qualified person-
nel. The manufacturer is not responsible for any eventual
damage or injury caused by inadequate skills during in-
stallation, or through removal of or deactivation of any
safety devices.
Function
Triac controller for proportional control of electric heating
TTC40F is a proportional, 3-phase electric heating controller with
automatic voltage adjustment. The controller operates through stepless,
time-proportional control, where the relationship between the on-time
and off-time is based on the current heat demand.
The controller is primarily intended for use together with Regin's NTC
series of sensors for either supply temperature control or room
temperature control. During room temperature control, the supply air
temperature can be provided with a minimum or maximum limitation.
TTC40F can control both symmetrical Y-connected 3-phase heaters and
symmetrical or asymmetrical Delta-connected heaters.
The controller is only intended for control of electric heating. The
control principle makes it unsuitable for control of motors or lighting.
TTC40F is intended for DIN-rail mounting.

temperature
Installation
– Mount TTC40F on a DIN-rail in a cabinet or other casing.
– Mount the controller vertically with the text right side up.
Note! At full power, TTC40F will emit approx. 70 W of ex-
cess heat which must be properly dissipated!
Wiring
– Connect the supply voltage to the terminals L1in, L2in and L3in.

Note! The controller must be grounded and the supply
voltage must be interlocked via a high temperature limit
switch!

Load
– Use terminals L1out, L2out and L3out.
– Resistive 3-phase heater without neutral connection.
Main sensor and external setpoint (figures 2-6)
– Use terminals 1 and 4 (polarity insensitive). Low voltage.
Note! Terminals 2 and 3 are internally connected and are
used to simplify wiring when using an external setpoint
potentiometer. Switch 1 is used to select internal or exter-
nal setpoint.
