NOTES:
1. D1 and D2 can be used independently for equipment requiring a
dry contact.
2. If humidifier or dehumidifier has its own low voltage power supply,
do not connect directly to the thermostat. Use isolated relays.
3. For humidifer control, 24-V is provided from the HUM terminal to
operate the equipment.
4. For dehumidifier control, 24-V is applied from Rc to the dehumid-
ifier through relay contacts D1 and D2.
