DECTRON
Some units may have optional hot-water or steam space heaters built in. Where the hot water or steam is
supplied by others, it is necessary to adjust the maximum flow.
To set the maximum flow, it is first necessary to put the unit into full heating mode. This is done by temporarily
changing the room-air temperature set point to a high value.

NOTICE
Risk of unit damage. Risk of failure to operate.
Excessive flow rates can damage heat exchangers.
Inadequate flow rates can cause failure to operate.
When the flows and temperatures are properly set, mark the adjusting device as having been set. Write the flow
rate here.
Return to the controller interface as above and return the room-temperature set point to the value recorded
above.
Be sure that the water or fluid temperature is near 180°F (82°C), and
not less than 160°F (71°C), unless otherwise specified by Dectron.
Note the size of the connections on the unit.
Adjust the flow rate to achieve the desired maximum space-heating
rate. Do not exceed the water flows shown here:
Connection Size Maximum Flow
1 ” O.D. or 1” NPT 16 GPM (60 l/m)
1 ” O.D. or 1 1/4” NPT 26 GPM (98 l/m)
1 ” O.D. or 1 1/2” NPT 36 GPM (136 l/m)
2 ” O.D. or 2” NPT 65 GPM (246 l/m)
2 ” O.D. or 2 1/2” NPT 101 GPM (382 l/m)
