7. Adjust the temperature setpoint from the
RNet Wall Sensor.
1. Read the Zone Temperature and adjust the
“Zone Heating Setpoint” at least 2°
above the ambient Zone Temperature. (You
can use the RNet Sensor). You should be able
to observe the Heat PID start increasing via
WEBCNTL (if it is being used). The MPC
should now be set to go into a Heating cycle.
a. When the PID value increases above
30% the SF (Supply Fan) LED for
the Supply Fan will illuminate on the
MPC unit.
b. When the PID rises above 40% the RV
(Reversing Valve) LED will illuminate
indicating the Reversing Valve has
cycled on.
c. If the Heating unit is wired to the unit
and thus not heating, the PID will
continue until goes above 90% and
then you should see Compressor 2
or C2 LED light up.
d. Decrease the Heating Setpoint 2°
below the Zone Temperature
and the Heating PID will begin to
move downward. (Check with
WEBCntl or BMS).
e. Once it falls below 90%, C2 will
turn off.
f. When it falls below 50%, C1 will turn
off and once it falls below 30% the
Supply Fan LED will turn off.
2. Read the Zone Temperature and adjust the
Zone Heating Setpoint at least 2°
above the ambient Zone Temperature. (You
can use the RNet Sensor or WEBCNTL for
this operation). You should be able to
observe the Cooling PID start increasing via
WEBCNTL as the MPC is set to go into
a Cooling cycle.
a. When the PID rises above 30% the SF
(Supply Fan) will illuminate indicating
the Fan has cycled on.
b. When the PID gets above 50%, the
Compressor C1 LED will illuminate
after a 2 Minute delay.
c. Decrease the Cooling Setpoint 2
degrees below the Zone Temperature
and the Cooling PID will begin to
move downward.
d. Once it falls below 50%, C1 will turn
off. Then nally when the PID goes
below 30% the SF will shut off.
