RWD44U/45U/62U/68U/82U
The RWD Controllers have standard, pre-configured applications. The respective application and setting parameters
are entered via push buttons on the controller or a software tool. See the individual Application Guides (available
online) or the Installation and Commissioning Guide for additional information. Use Tables 1 through 12 to determine
the appropriate controller model and application number.
Example: Select an application that controls two stages of electric heat and two stages of digital cooling, and
includes remote setpoint and an alarm to signal dirty air filters.
1. Select a controller based on the number of outputs and characteristics required. In this example, four digital
outputs are required. Select the RWD44U Controller (see Table 1).
Table 1. Controller Models.
Outputs
Controller Model Analog 0 to 10 Vdc Digital
RWD82U 0 2
RWD62U 2 0
RWD68U 1 1
RWD44U 0 4
RWD45U 1 4
2. Determine the main control loop. Select an application number based on the output characteristics. For the
RWD44U Controller, main control loop 1X (application group 10 through 19) contains the output characteristics
that match this example (see Table 3).
3. Determine the auxiliary control loop. In this example, an auxiliary control loop (X1) is required to readjust the
setpoint remotely (see Table 4).
The controller model and application number needed for this example is RWD44U, Application #11.

NOTES:
1. The heating sequence output is set to Direct Acting (default). This is typically used for normally open valves.
Output can be set to reverse acting by changing the MIN and MAX value.
2. The cooling sequence output is set to Direct Acting (default). This is typically used for normally closed valves.
Output can be set to reverse acting by changing the MIN and MAX value.
