How to connect / wire a off delay timer with a 3 phase contactor ?

thanks
Update: seven (7) heaters , 3 phase supply , Digital temperature controller of P + D type , K type thermocouple for heat sensing , a Off delay timer of 0.1 sec to 30 sec , a 3 phase contactor of 220 V coil , digital temperature controller of 220 V ac supply ..... From 3 phases , each single phase goes to 2 heaters each... show more seven (7) heaters , 3 phase supply , Digital temperature controller of P + D type , K type thermocouple for heat sensing , a Off delay timer of 0.1 sec to 30 sec , a 3 phase contactor of 220 V coil , digital temperature controller of 220 V ac supply .....

From 3 phases , each single phase goes to 2 heaters each (pair of 2 heaters) & the third phase goes to the 3 pair heater (pair of 3 heaters) , the neutral is common to every heater ........

the output of the Digital temperature controller , one of them goes to the off delay timer & one goes to the coil of the 3 phase contactor . I couldn't understand this


Kindly tell me how to reconnect these things together to complete the task of controlling the heater & blower system , blower also 3 phase

thanks
