Applications
|
- Comfort and Convenience
- The ZTT000 Wall Mounted Thermostat can be operated by mode buttons on the face of thermostat or by your HomePro
Wireless Controller to adjust temperature set point or change the modes. Control it from your easy chair.
- Control Modes
- Electric Heat: Allows one stage
- Auto Changeover Mode: Will automatically change from heating to cooling and vice versa
- Gas or Oil Heating: Allows one stage
- Dry Air Mode: Cycles compressor and fan to reduce humidity
- Cooling Mode: Allows up to two stages
- Fan Only: Operates fan (only) in High or Low setting
- Heat Pump: Allows up to two stages
- The Timer: Daily thermostat ON and OFF times (can set in 10 minute increments by by Timer button on thermostat)
|
In this mode, the fan can be set in any of its four modes: Low, High, Auto Low or Auto High. If electric heat is in addition to a heat pump, the HEATING ACTIVE REVERSE VALVE, output “B”, will be ON all the time ELECTRIC HEAT mode is selected.

Operating Modes:
|
- Electric Heat Mode:
- In this mode, the fan can be set in any of its four modes: Low, High, Auto Low or Auto High. If electric heat is in addition to a heat pump, the HEATING ACTIVE REVERSE VALVE, output “B”, will be ON all the time ELECTRIC HEAT mode is selected.
- Auto Change Mode:
- In this mode, the system will change from COOL mode to ELECTRIC HEAT mode automatically in relation with room and
Set Point temperatures. If room temperature rises above Set Point, the system will automatically switch to COOL modeand it will operate accordingly.
If room temperature drops below Set Point by 3ºF, the system will automatically switch to ELECTRIC HEAT mode. Set
Point will be “shifted” below by 3ºF and the system will follow ELECTRIC HEAT mode.
In this mode, the fan can be set in any of its four modes: Low, High, Auto Low or Auto High.
- Gas or Oil Heal (Furnace) Mode:
- The system will cycle heat output in relation to the room and Set Point temperatures. The HEAT, output “W2”, will turn ON if the room temperature drops below Set Point by 1ºF. “W2” will turn OFF if room temperature rises above Set Point by 1ºF. There is no fan selection in this mode.
- Dry Air Mode:
- The system will cycle the compressor output in relation to the room and set point temperatures during specific periods, in order to remove moisture from the ambient.
If room temperature rises above set point by 1°F, COMPRESSOR and LOW speed fan, outputs “Y1” and “G”, will turn on for 15 minutes then off for 3 minutes and will continue this cycle until the set point temperature is satisfied. A sample reading of the room temperature is taken immediately after every cycle to determine whether or not to start another cycle. Set point is ignored during timing cycle.
If the room temperature drops below set point, “Y1” and “G” outputs will turn on for 6 minutes then off for 15 minutes and will continue this cycle until the set point temperature is satisfied. A sample reading of the room temperature is taken immediately after every cycle to determine whether or not to start another cycle. Set point is ignored during timing cycle
If temperature of sample reading is below Set point by 5ºF or more, pause for additional 15 minutes, sample temperature, and based on temperature relative to set point, cycle or pause 15 minutes, until user decides to stop mode.
- Two Stage Cooling Mode:
- In this mode, the fan can be set in any of its four modes: Low, High, Auto Low or Auto High. If a heat pump, the COOLING ACTIVE REVERSE VALVE, output “O”, will be ON all the time COOL mode is selected. The system will cycle the compressor outputs in relation to the room and set point temperatures.
The FIRST STAGE COMPRESSOR, output “Y1”, will turn ON if room temperature rises above Set Point by 1ºF and the
Delay on Break time has already elapsed. “Y1” will turn OFF if room temperature drops below Set Point by 1ºF.
The SECOND STAGE COMPRESSOR, output “Y2”, will turn ON if room temperature rises above Set Point by 2ºF and
the Delay on Break time has already elapsed. “Y2” will turn OFF if room temperature drops below Set Point by 1ºF. There will be a 30 second Delay on Make between actuation of “Y1” and “Y2” outputs.
- Fan Only Mode:
- In this mode, only the FAN output will operate by selecting Low or High speeds.
- Two Stage Heat Pump Mode:
- The system will cycle the compressor outputs in relation to the room and set point temperatures. The FIRST STAGE
COMPRESSOR, output “Y1”, will turn ON if room temperature rises above Set Point by 1ºF and the Delay on Break time
has already elapsed. “Y1” will turn OFF if room temperature drops below Set Point by 1ºF.
The SECOND STAGE COMPRESSOR, output “Y2”, will turn ON if room temperature rises above Set Point by 2ºF and
the Delay on Break time has already elapsed. “Y2” will turn OFF if room temperature drops below Set Point by 1ºF.
There will be a 30 second Delay on Make between actuation of “Y1” and “Y2” outputs.
