Configuring the Keypad/Display page
Use the KeyPad/Display Configuration page to configure
the keypad lockout level, display temperature unit in the
thermostat, time display format, system switch configuration
and fan switch configuration.
Mode
Configuration can be performed with the wizard Off-line or
On-line.
Procedure
1. Click the Keypad button on the left pane to open the
Keypad/Display Configuration page.
2. Enter information into available fields (see Table 71 on
page 101).
3. Click Commit to save the settings or Reset to revert to
the last saved settings.
4. Click Next to display the Setpoints Configuration
page or Back to display the General Configuration

Heat/Cool
Stages
(continued)
When the model is selected as T7350H1009 and the equipment type as Standard, the tool allows to configure for
up to three stages of heating and three stages of cooling. The fourth stage of cooling is available for selection as
long as the 0/1/2 heat stages are selected. When the fourth stage of cooling is selected, the third stage of heating
is no longer available.
When the model is selected as T7350H1009 and the equipment type is selected as Heat Pump, you will have
option to configure for 0/1/2 auxiliary heating stages and 0/1/2 compressor stages. One relay is used for heat
pump reversing valve.
When the model is selected as T7350H1017, you can configure for 0/1/2 heat or cool stages. The modulating
outputs are always active. They are always being driven 0-100%. When the number of stages is 0, the relay
outputs are used to enable the heating or cooling outputs. Staged action may be used in addition to the
modulating outputs. The number of stages is set to 1 or 2. It is not possible to have both 2 stages of heating and
cooling.
Examples:
1. Selecting heating stages and cooling stages as 1 configures for modulating heat and modulating cool
action.
2. To have Mod heat, heating pump enable relay and 1 stage of heating, configure Heat Stages as Heat
Enable, Heat Action (depends on the actuator connected) and connect the relay W1 such that it turns the
heating pump ON or OFF.
Aux DO Use this option to configure the auxiliary outputs. The auxiliary DO can be configured for economizer, Time Of
Day or for dehumidification. The dehumidification options available are Simple dehumid or Dehumid Hotgas BP.
In the case of T7350H1017 model type, the auxiliary DO can be configured for second stage of heating or
cooling. In that case, it cannot be configured for the above mentioned purposes and hence the option is disabled
in the screen.
NOTE: The dehumid options (Simple dehumid or Dehumid Hotgas BP) are available for configuration only if a
humidity sensor is configured.
Heat Pump
Rev Value
This option is available for T7350H1009 model when the Equipment Type is selected as Heat Pump.
The options available are:
Active Cooling
Active Heating
Select Active Cooling when the O/B valve is energized on cooling or Active Heating if the O/B valve is energized
on heating. If the standard application is configured, this option is not available.
Heat
Action
This option is available for model is configured as T7350H1017 only.
This is disabled when the model is selected as T7350H1009. This is applicable for modulating heat output, that is
when the Heat Stages option is configured as Heat Enable.
Select Direct 4-20mA if the actuator connected for heating action is driven from 0-100% and Reverse 20-4mA if is
driven from 100-0%.
Cool
Action
This option is available for model is configured as T7350H1017 only.
This is disabled when the model is selected as T7350H1009. This is applicable for modulating cool output, that is,
when the Cool Stages option is configured as Cool Enable.
Select Direct 4-20mA if the actuator connected for cooling action is driven from 0-100% and Reverse 20-4mA if is
driven from 100-0%
