The housEvolve System

Compatibility information:

• Model he_th_st1 supports all standard 1Heat/1Cool, single-return, 24Vac HVAC systems. Many dual-return systems are also supported, please contact us for more information if your HVAC system falls into this category
• Model he_th_hp1 supports 24Vac, single-stage Heat Pump HVAC systems with or without auxiliary heat.
• Model he_th1 provides support for either of the above HVAC system categories, selectable through the user interface.

Please note: Modern digital thermostats require a connection to the HVAC "Common" terminal for power. All housEvolve thermostat models also require this connection, but only in Stand-Alone mode. This connection is optional when used with a housEvolve Main Controller because power is also available through the housEvolve system connection. This makes housEvolve thermostats directly compatible with many older thermostat cables and HVAC system configurations.

Thermostat as a Stand-Alone product:

• Fully programmable digital thermostat (daily, weekday, weekend; 9-event program capability)
• Automatic HVAC state changeover (Heat-A/C)
• Two-stage display backlight system allows for no-touch viewing in most lighting conditions
• Simple, 5-button user-interface

Thermostat used with a housEvolve Main Controller:

The housEvolve thermostat becomes fully interactive, providing remote access to its capabilities.

1. Monitoring. All current thermostat settings are available remotely:


• Current temperature reading
• Current target temperature setting
• Current HVAC operating mode (Ex: Heat, A/C, Fan, Off)
2. Control. Change thermostat settings remotely:


• Set the thermostat's target temperature, over the phone, to any value in the allowed range (45-85 degrees).
• Set the HVAC system operating mode over the phone
3. Alerts. Become aware of temperature-related problems in you home as soon as they emerge. The housEvolve system will call you to report the following conditions:


• Temperature-out-of-bounds Alert. Issued if the indoor temperature falls 5 degrees or more below the thermostat's set temperature in Heat mode, or if the indoor temperature rises 5 degrees or more above the thermostat's set temperature in A/C mode. This is an extremely useful early-warning feature, indicating a problem with the HVAC system (ex: malfunction, out of fuel, etc), or the impact of a prolonged power outage condition in your home
• Freeze Alert. Issued if the indoor temperature falls below 40 degrees, regardless of HVAC operating mode (Heat, A/C, Off)
• Overheat Alert. Issued if the indoor temperature climbs above 90 degrees, regardless of HVAC operating mode (Heat, A/C, Off)
• Power Failure Alert. Issued to alert the user to the fact that the HVAC system is currently off-line due to lack of power
In addition, the housEvolve system's Rechargeable Battery Backup Feature allows uninterrupted remote access to the thermostat module under power failure conditions for extended periods.

NOTE: Multiple thermostat modules may be used with a housEvolve Main Controller to support zoned climate control applications.
