• Terminal blocks represent the most common application. Please check the application table first
•The relay output are line voltage, they are connected with line voltage internally inside thermostat
•The OCC terminal can assume different meaning depending on parameter 17 setting
• The functionality of the remote NTC is depending by P25 and P16 parameters
Alarm Code Description
Item Code Description
1 E1 Internal sensor shorted warning
2 E2 Internal sensor opened warning
3 HI High temperature warning. Room Temperature > 55℃
4 LO Low temperature warning. Room Temperature < 0℃
5 E3 Remote sensor shorted
6 E4 Remote sensor opened
7 E5 Dew point risk warning
· E3,E4 only available for 2-pipe, auto mode enabled.
· icon will twinkle if there is filter alarm
· COM symbol will ash if there are communication fault
· If the remote sensor is enabled, the E1/E2 warning will be ignored. If E1/E2 warning happened, T7000 will shut off the fan and close the valve.
