Cooling or Heating
CTE-5202 thermostats can use MEP-4xx2 actuators
to operate damper boxes in a pressure-dependent
VAV system. As shown in the diagram, a “requested
ow” voltage signal (AO1) is connected to the MEP-
4002 to adjust airow from minimum to maximum
ow according to space demand. Minimum and
maximum ow limit adjustments can be made at the
thermostat (recommended) or at the actuator. (See
the MEP-4000 Series Installation Guide.)
For cooling, select Sequence 1 (from the CTE-5202
SYSTEM menu). See Change Conguration on
page 6.

Select Sequence 1 Select Sequence 1
AND set Changeover to 55° F
For heating, connect a 5K to 10K ohm resistor
between Common and AI1. Select Sequence 1 and
lower the Changeover to the lowest seing (55° F).
See Change Conguration on page 6. The resistor
simulates a changeover sensor and puts the thermo-
stat in Reverse Acting mode.
NOTE: If the resistor value is too high, the
thermostat will not go into RA mode. If
the resistor value is too low, the thermostat
may go into setback mode.
