Comfortmaker - NAXA00101DB - Thermostat, Daughter Board

The NAXA00101DB daughter board control allows for using 4 existing thermostat wires in an existing, finished home to communicate with the TSTAT0406 & TSTAT0407 thermostats. The daughter board translates the communicated heating and cooling needs and sends the normal discrete thermostat outputs to the indoor and outdoor equipment as needed. The NAXA00101DB Daughter Board must be used in conjunction with the TSTAT406 or TSTAT0407 Communicating Thermostat for proper operation. The daughter board provides a two-wire RS485 ModBus communication link and 24VAC to the communicating thermostat via a 4 wire connection scheme, “L” input from the Comfort Alert Module, a sensor input for the remote outdoor sensor, seven thermostat 24VAC outputs (W,G,Y,O,W2,Y2,H) and status & communication LED’s.
