HMI Hoyme ADP- 1101 - 05A  
Adaptor control centre combines 120Vac with 24Vac circuits. Interconnects the thermostat fan cycle, primary exhaust fan switch and the furnace circulating fan. Fresh air damper, if installed, also opens simultaneously with exhaust fan. Will not interfere with air conditioning controls. C/W 120Vac coil with 24Vac switching for 24Vac dampers and thermostat circuits.

HMI Hoyme ADP- 0241- 05A / 10A  
This Relay Adaptor may be used as an automatic switch having a 24Vac coil and 120Vac contact points to control a line voltage circuit for either a 5 or 10 amp draw. i.e. Exhaust Fan. Adaptor can also be used 100% for 24Vac switching (See ADP-1101). Switching 24Vac dampers and thermostat circuits use 5A type only and for 120Vac fan control, use 10A type only.
