I bought the 'T8011R1006' programmable Digital Thermostat to replace my existing 'T874R1822', Analog Thermostat that controls a 2-Stage Heating and 1-Stage Cooling Electric Heatpump, The Sub-base model of the existing thermostat is 'Q674L1710'. The volts going into the thermostat is 24V. The thermostat also controls central Air Conditioning. The available terminals on the old analog thermostat are W2, W3, L, O, X, R, Y, E, G and B. There are 7 wires going into the W2, L, O, X, R, Y and G terminals and there is also a cross connection between the W2 and E terminals. In the new Digital thermostat 'T8011R1006' the available terminals are: W1, W2, L, O, C, R, Y, E, G and B. My doubts in the wiring are:

(1) Since there is no X terminal in the digital thermostat I bought, can I make the same connection to the C terminal?
(2) The connection to the W2 terminals from the analog thermostat should go into the W2 terminal in the digital thermostat as well, isn't it?
(3) Should I make the cross connection between W2 and E in the digital thermostat as well?
(4) All the other connections from the analog thermostat would be mapped one-on-one in the digital thermostat as well, isn't it?
