User manual HONEYWELL T7560A

[. . . ] Disconnect the power supply before making connections DWM DISASSEMBLY The T7560A, B, C comes packed with a sub-base that mounts separately for ease of installation. The cover is fixed by a latch on the underside of the unit. Insert the tip of an awl or a similar narrow, pointed object into the small hole in the latch (T7560A, B) or simply depress the latch by hand (T7560C). Pry off the cover. to or removing connections from the DWM's terminals. Do not reconnect the power supply until you have com- pleted the installation. If the DWM is powered via terminal 8 and connected to earth ground, then the cable must be shielded. Observe precautions for handling electrostatic sensitive devices.

Fig. Mounting cover of T7560A, B DWM CAUTION Low Voltage Equipment. The 24 Vac power source for the DWM must be a Class II Power Source. To conform to Class II restrictions, transformers must not be larger than 100 VA. A transformer that is CE certified and meets the Low Voltage Device (LVD) requirements must be used in Europe for all installations of this product. The DWM power usage is < 0. 2 VA at 24 Vac. The DWM does not require a dedicated transformer. The DWM can get power from any convenient location in the 24 Vac power circuit. The 24 Vac power can come from the 24 Vac power terminals on the nearest controller or directly from a 24 Vac transformer, whichever is closer. When all wiring is complete, attach the cover of the DWM as is shown in Fig. NOTE: Make sure that the latch on the underside of the DWM engages properly.

This is done by using the buttons and the setpoint wheel (see Fig. 7). In the following, default settings are marked with an asterisk (*). P1 Setpoint Type Setting / Scale Type Setting · Fahrenheit relative · Fahrenheit absolute Celsius relative * Celsius absolute · P2 · * · Room Temperature Setting Do not display room temperature (setpoint, only) Display room temperature Display room temperature and humidity, alternating every 5 seconds (T7560B, only) Bargraph Use Setting No Fan Auto, Off, On Auto, Off, 2 Speeds Auto, Off, 3 Speeds Controller Type Setting New LCD signaling from controller (only for controllers and SW versions as listed in Table 2 or higher, in which case this setting must be selected; set Excel 10 controller to LCD_DISPLAY) LED override mode from controller, US signaling (100 ms pulses); with contr.

After power-up, all display segments are switched on for approx. [. . . ] Default (if set to Celsius): Default (if set to Fahrenheit): Example (units set to Celsius): A setting of means that the set point offset is limited to -3 to +3 °C. Example (units set to Fahrenheit): A setting of means that the set point offset is limited to -8 to +8 °F. Limit for humidity low limit output value Limit the output value to 10 . . . This affects the output voltage on pin 7, only, and has no effect upon values appearing in the display. [. . . ]
