Mounting
Connections and Wiring
Wire as shown for providing proportional reheat
to an electric hot water valve with an MEP-3001
actuator. Supply the relay with 24 VAC (+20%/–15%)
from a Class 2 transformer. (Use wire size of 14 to 22
AWG, stranded.)
The fan starting point is adjustable so that optimum
use can be made of the warm air in the return air
plenum before opening the hot water valve. A DC
voltmeter is shown across “X” and “9” terminals.
This can be used to measure the fan setpoint for
recalibration. The setpoint is factory-set at 2.5 VDC.
(Do not set the fan setpoint below 0.6 VDC, or else
the fan may lock in the On position.)
