    Baysys SZ1017a

    I want to replace an "in use" modulating thermostat Basys sz1017a with a touchscreen thermostat from Honeywell or White Rodgers (preferably). What choices do I have? System is a 2 stage electric heat (2 stage electric heating module is mounted in the air handler) and cooling is handled via a roof top chiller unit (Carrier). sz1017a is currently wired using "Y1 or W1", "Y2 or W2", A01 and GND wires connect to HWV or CWV, also a remote room sensor is installed on terminals T1 and T1. power - 24VAC single transformer.
