TEC 100/200 with Monitor Socket
The TEC 100/200 is available with a pre-wired Monitoring Socket. In such a
case, the control wiring must be as shown in Fig.3 (page 5).
The power supply to the unit must be from a permanent source to enable the
monitoring system to function in the correct manner.
Within the TEC 100/200 you will see an orange fly lead. This should be
connected to the timeswitch output to provide a signal for the demand meters
(lower set).
If for any reason the system will not allow connections into the control
thermostat as shown in Fig.3, then remove the red link wire as shown in Fig.9.
Connect the white fly lead to the now spare connector on the monitor socket
(originally connected to red link), and connect directly to burner supply to
provide a signal for the firing meters (upper set).
The monitoring system has an integral digital timer that has been programmed
to operate the Day On/Day Off changeover at 00:05 – 00:10 hrs. Open the
monitor lid and operate the change button on the digital timer to initiate an
active period (red LED off).
With the boiler firing and the heating timeswitch on, the two active meters
should be operating. The top active meter indicating firing hours, and the
bottom active meter indicating demand hours.
If they are not operating, re-check all connections.
Allow the TEC 100/200 to reach Temp Set mode (boiler cut-off), and note the
firing meter has stopped. Operate the change button on the digital timer to
initiate a bypass period (red LED on). Providing that the boiler thermostat
is on, the boiler will re-fire (TEC 100/200 bypassed), and the bypass meters
will operate. The top bypass meter indicating firing hours, and the bottom
bypass meter indicating demand hours.
When ready to start the monitored test, operate the change button on the
digital timer to enter an active period (red LED off), ensuring that the timer is
itself in the off state. If necessary, reset the hour meters to zero with the reset
button provided in the top right hand corner of the unit. The system will now
