1.3 THE PRODUCT’S STRUCTURE AND OPERATION
1.3.1 General description
TEHs, placed inside the Product (see Figures 1 and 2), heat the air causing
natural convection within the heated spaces.
The Product is additionally equipped with:
1) capillary temperature controller (with adjustable threshold of actuation) TC-1,
which temporarily switches TEH off, once air temperature reaches the preset one;
2) temperature fuse (sensor-relay) ТF-1, which prevents the Product casing from
overheating by disconnecting TEH power circuit.
Х1 –terminal block to connect power supply network (127; 220; 380 V AC);
S1 –power breaker (switch); E1–E6 –TEHs
Figure 1 –Structural diagram of the Product, UT-S type
Note –TEHs E1–E2 are installed on UT-300S, UT-600S and UT-800S types,
E1–E4 –UT-1200S types, E1–E6 –UT-1800S type.

Notes
1 TEHs E1–E8 are installed on UT-300C, UT-600C, UT-800C and UT-1200C
types, E1–E4 –to heaters UT-1800C type.
2 TEH power of UT-1800C type is higher than others, therefore number of
TEHs is smaller.
1.3.2 Controls and indication
The following controls and LEDs are located on the Product casing:
knob of temperature controller TC-1 (see 1, figures 3, 4) to set required air
heating temperature;
power piano type on/off switch (see 3, figures 3, 4) with an integrated LED
displaying Product operation.
