PURPOSE OF THE RELAY
 Temperature relay TR-15 is designed to control and maintain the preset temperature mode at the temperature sensor signals, generated on the basis of the chip DS18B20 Dallas Semiconductor (Maxim) in the premises, vegetable storage, water heating systems, cooling systems, liquids, objects, and so on, and also for use as components in the automation devices.
 
DESIGN OF THE RELAY
 The relay is produced in a hermetic a plastic case. The lower part of the case there are pressure seals for cables of power supply and switched circuit. Mounting is carried out on a smooth surface. To install the relay, you must remove the transparent front cover, through the holes located at the corners of the case, fix the sleeve with four screws M4. Terminal design of supply provides robust clamp wires up to 1,5mm2. Terminal design of switched circuit provides robust clamp wires up to 3,31mm2. On the board of device there are: two rotary switches for setting temperature "t0С" (setting values units 0-9 and tens 0-9), switch "+t/∆" for setting a positive or negative temperature, husteresis zone and mode of operation  (cooling - heating), red LED "+t"  of heating mode, blue LED "-t"  of cooling mode, yellow LED of enabled executive relay.
 
 WARNING: It is forbidden to carry out any work with the relay under voltage.
 
OPERATION OF THE RELAY
 Termorelay can work in two modes: "heating" or "cooling".
 "Heating" - a mode in which the executive relay is turned on, if the controlled temperature is below the set (heater).
 "Cooling" - a mode in which the executive relay is turned on, if the controlled temperature exceeds the set limit (fridge).
 The operating mode is selected by switch "+t/Δ", first five switch positions corresponds to the cooling mode "Cooling", the following five positions of  switch heating mode "Heating". Enabling of the executive relay is controlled by a yellow indicator. When the relay is turned on, the yellow LED lights up and the contacts are closed. In "heating" mode when power is turned on, if the temperature in the controlled point will be below set, the relay will turn on. Upon reaching the set temperature (t0Cset) - the relay will switch off. When cooling, the re-activation of the relay will take place at t0Cset - Δ (taking into account the hycteresis). In the "cooling" mode at power up, if the temperature in the controlled point will be above the set, the relay will turn on. Upon reaching the set temperature a relay turns off. At the next time of the temperature increases, the relay will turn on at temperature t0Cset+ Δ (taking into account the hysteresis).

 Setting the range of temperature and hysteresis by switch «+t/∆»:
  • «100+t/2» - range from +1250С to +1000С hysteresis 20С
  • «+t/2» - range from +990С to +00С hysteresis 20С
  • «+t/0.5» - range from +990С to +00С hysteresis 0,50С
  • «-t/2» - range from –550С to -00С hysteresis 20С
  • «-t/0.5» - range from –550С to - 00С hysteresis 0,50С
 Control of operating modes is carried out on indicators.
 
 WARNING:  If using more that 7500W power devices is recommended to use intermediate relays or contactors, the appropriate load.
