HAI's Thermostat Isolation Module (HAI Part Number 29A00-1) provides relay isolation for Omnistat RC-80B thermostats. This optional module may be needed for HVAC systems using non-standard voltages.
HAI's Thermostat Power Supply Module (HAI Part Number 30A00-1) provides a power booster for Omnistat RC-80B thermostats. This optional module may be needed in retrofit applications where "HVAC common" wire is not available.
This Omnistat has the following remote control features:
|
- 4 communications modes, selectable during installation: 2 serial modes for connection to home automation systems, building management systems and personal computers, and 2 voltage signal modes for connection to time clocks, remote setback switches and many burglar alarm panels
- Data signal is electrically isolated from heating and cooling system for superior reliability in all modes. Fully interactive with all HAI manufactured controllers, including mode, heat setting, cool setting, fan and hold settings. (Serial Mode 1)
- Can communicate directly with the RS-232 port of a personal computer - no adapter required. Serial mode protocol: addressable up to 127 units, bi-directional, 1 start bit, 8 data bits, 1 stop bit NRZ. 300 baud data rate. Can communicate continuously without loss of function. Protocol is available from HAI web site. (Serial Mode 2)
- Remote selection between Day and Night settings: a remote signal (12 VDC) selects between user programmed "day" and "night" settings for both heating and cooling modes. The settings can be changed by a user, but they will return to the preprogrammed ones on application (for night) or removal (for day) of the signal. Ideal for use with time clocks, building management systems, access control systems, alarm systems to set to preprogrammed temperatures when building is unoccupied. (Voltage signal mode 1)
- Thermostat Override: a remote signal (12 VDC) overrides the thermostat operation and turns off the HVAC system. Removal of signal restores normal operation. Remote indicator shows that thermostat is overridden. Safety feature will turn on heat if temperature drops below 45 degrees F. (Voltage signal mode 2)
