SIEMENS RDG160TU Commercial Thermostat Instruction Manual

Selecting Location

Install the thermostat about 4 feet (120 cm) above the floor on an inside wall. Ensure that there is free airflow around the thermostat. Do not install the thermostat near windows or doors, in direct or radiant heat of sunlight, on unconditioned outside walls or near heating or cooling duct outlets. Not following these prerequisites will adversely affect the thermostat’s sensed temperature and its control performance. See Figure 1

Figure 1. Mounting Location.

Installation

Step 1. Loosen retaining screws.

Step 2. Remove thermostat from back plate, if attached.

Step 3. Mount back plate at desired location and terminate wiring connections. See maximum wire size (above).

Step 4. Set application DIP switches. See DIP Switch Settings.

Step 5. Pivot thermostat onto back plate.

Step 6. Snap into place and tighten mounting screws.

Setting Up Applications

Use the DIP switches to set up Basic Applications.
Use the Control Parameter set up on the front panel to set up additional application customization or special set up can be set up. See Parameter Set Up in Service Level.

If no Applications are set up, the front panel displays NO APP.

Diagnostics Mode

In addition to standard Service level control parameter set up, the RDG160TU also has an Expert Level for the advanced user to perform diagnostics and troubleshooting. SeeTable 3.

DIP Switch Settings Overview

Applications are set up with DIP switches 1 through 3.
DIP Switch 4 selects ECM Fan (OFF) or 3-Speed Fan (ON).
DIP Switch 5 (ON) disables time program functions; time is not displayed.

Following is the set up of the most common applications and any supporting parameters to be set using the Service Menu after installation. For other application settings or detailed control functions, see Room Thermostats with LCD for Wall Mounting RDG100, RDG100T, RDG110, RDG140, RDG160, RDG100T/H Basic Documentation (CE1P3181).

Parameter Set Up in Service Level

To change control parameters, do the following:

1. Press the HEAT/COOL and FAN/OK buttons simultaneously for at least 4 seconds.
2. Release them and, within 2 seconds, press the HEAT/COOL button again until P01 displays.
3. Select the required parameter by turning the rotary knob.

5. Press the FAN/OK button to confirm the adjusted value or press the HEAT/COOL button (Esc) to cancel the change.

6. To adjust additional parameters, repeat Steps 3 through 5.

7. Press the HEAT/COOL button (Esc) to exit the parameter setting mode.

To return to the factory-default control parameters, do the following:

1. Change the value of Parameter P71 to ON.

When reloading, the screen displays 8888.

NOTES

• Parameters P46 and P47: Use DIP switches 4 and 5 to set to 2-position or 3 position.
• Parameter P45 compensates for heat dissipation of the electric heater relay.
• If no sensors or switches are connected, it is not necessary to disable the inputs (P38, P40 or P42 = no function), the thermostat recognizes if a sensor is connected (but diagnostic displays Err).
