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
