Programming options for TE 7272 D are simple, targeting ones needs with clear programming algorithm.
The value of Seti can be adjusted just with buttons and Value can be increased or decreased one by one pressing the buttons at a time. If one of the buttons are pressed continuousiy for 3 seconds adjustment can be done more faster. After adjustment is done the new value for Seti is stored in the memory.
After PRG button is pressed for 5 seconds ST2 value will be di- splayed and buttons are used to adjust St2.
Second time the PRG button is pressed rl2 option is displayed and Set2 can be activated (ON) or de-activated (OFF) with and buttons.
Third time the PRG button is pressed rl2 option with two choices:h ı or Lo are displayed and can be selected with and When Lo is selected relay2 is activated when the temperature is belovv the valueof set2. If h ı is selected then relay2 will be activated when the tempe rature is equal or higher then that of set2.
Fourth time the PRG button is pressed HYH option is displayed. With and buttons the rate band value can be selected between1 ° Cto20 ° C
Fifth time the PRG button is pressed dt option is displayed. With and buttons the rate time value can be selected betvveen 2 seconds to 20 seconds.
If none of the buttons are pressed for a vvhile the thermostat will automatically store the changes and set back to normal operating mode
Time Rate Operating Mode
Rate band value (HYH) sets the temperature difference for which the time rate operating will be activated before the value of Seti.Time rate value (dt) sets the period time in seconds for relayl in time rate operating mode.
Example: HYH= 10 ° C, dt= 6 sec. And Set1=200 ° C At temperature Seti - HYH = 200 ° C -10 ° C = 190 ° C time rate operating mode starts and stops at Seti + 2 = 202 ° C. The ON and OFF time for the relay is half of the period at 196 ° C (thats 3 sec. ON and 3 sec. OFF).
