EasyTouch 2.5 Operations Manual
Rev 1.0 8/27/14
11.1.1 High Fan Speed (35-95;
95
)
Selecting this parameter immediately turns on the fan at manual high speed so you can
assess the sound and air flow while adjusting. The high fan speed can be adjusted from 35
to 95. Select a higher value to increase the fan speed or a lower value to decrease the fan
speed. Adjusting this parameter has no effect on the other two fan speeds. Once the setting
is saved via the SAVE button or the setting screen is exited via the BACK or HOME buttons
(or via Sleep Mode), the fan speed returns to the previous state.
NOTE: It is possible to adjust the high fan speed to be lower than the medium or low fan
speed, so please take this into consideration when adjusting all three speeds.
11.1.2 Medium Fan Speed (32-85;
61
)
Selecting this parameter immediately turns on the fan at manual medium speed so you can
assess the sound and air flow while adjusting. The medium fan speed can be adjusted from
32 to 85. Select a higher value to increase the fan speed or a lower value to decrease the
fan speed. Once the setting is saved via the SAVE button or the setting screen is exited via
the BACK or HOME buttons (or via Sleep Mode), the fan speed returns to the previous state.
NOTE: It is possible to adjust the medium fan speed to be lower than the low fan speed or
higher than the high fan speed, so please take this into consideration when adjusting
all three speeds.
11.1.3 Low Fan Speed (30-75;
50
)
Selecting this parameter immediately turns on the fan at manual low speed so you can
assess the sound and air flow while adjusting. The low fan speed can be adjusted from 30 to
75. Select a higher value to increase the fan speed or a lower value to decrease the fan
speed. Once the setting is saved via the SAVE button or the setting screen is exited via the
BACK or HOME buttons (or via Sleep Mode), the fan speed returns to the previous state.
NOTE: It is possible to adjust the low fan speed to be higher than the medium or high fan
speed, so please take this into consideration when adjusting all three speeds.
11.1.4 Inside Temp Calibration (±50°F or ±25°C;
0 [no adjustment]
)
This parameter calibrates the currently selected inside temperature sensor within a range of
±50°F or ±25°C. Adjust this parameter to display the correct room temperature reading by
using a calibrated temperature measurement device for comparison.
11.1.5 Temperature Units (AUTO/°F/°C;
AUTO
)
The AUTO selection sets EasyTouch to display all live temperatures and temperature
settings in °F (Fahrenheit) when connected to 60Hz AC power and in °C (Celsius) when
connected to 50Hz AC power. AUTO makes this units selection only during AC power up.
To set EasyTouch to use °F or °C all of the time regardless of the AC power frequency, select
either of those two settings options.
11.1.6 Reversed Fan Speed in Heat (OFF/ON;
ON
)
Reverse Fan Speed reverses the automatic fan speed behavior during a heating cycle in
AUTO or HEAT Modes. This is to improve heat output in cold ambient conditions. When set
to ON, the automatic fan speed will decrease as the inside temperature moves away from
(below) the set point, and the fan speed will increase as the temperature approaches the set
point. Using a lower fan speed when the cabin is cold increases the system head pressure
and helps raise the supply air temperature. Using a higher fan speed as the set point is
approached also reduces unnecessary high-pressure faults. The fan switches back to low
speed (continuous) or turns off (cycled) once the set point is satisfied and the heating cycle
terminates. Alternately, the automatic fan speeds during a heating cycle can be programmed
to operate the same as in a cooling cycle by setting this parameter to OFF.
