Display and DIP Switches

DIP Switches

Lock / Unlock (DIP Switch #1)

Use the Lock / Unlock DIP switch to lock or unlock the Access Level of the 162.

• To unlock the Access Level, set the DIP switch to the unlocked (left) position.

• To lock the Access Level, set the DIP switch to the locked (right) position. Once locked, a padlock is displayed in the lower right corner of the display and the Access Level cannot be changed.

Note: The tN4 System Control’s Lock / Unlock DIP switch

overrides the Lock / Unlock DIP switch on the 162. Set the tN4 System Control’s Lock / Unlock DIP switch to the Unlock position before Access Levels can be changed on the setpoint control.

tN4 System Control (DIP Switch #2)

A tN4 System Control is a control, not a thermostat, that the Setpoint Control 162 connects to through the tN4 bus. All tN4 compatible Outdoor Reset Modules are tN4 System Controls.

• If the thermostat is connected to a tN4 System Control, set the tN4 System Control DIP switch to tN4 System Control (left position).

• If the thermostat is not connected to a tN4 System Control, set the tN4 System Control DIP switch to None (right position).

Access Levels

•

The Access Level restricts the number of Menus, Items and Adjustments that can be accessed by the user. The Access Level setting is found in the Miscellaneous (MISC) menu. Select the appropriate access level for the people who work with the setpoint control on a regular basis.

The 162 has five Access Levels:

• Advanced (ADV): access to all settings

• Installer (InST): settings required for installation

• User (USER): for property owners

• Limited (LTD): limited temperature adjustment

• Secure (SEC): for commercial and public installations

In the Limited access level, the temperature can only be adjusted by +/-3°F (1.5°C) from the temperature setting entered prior to entering the Limited access level.

In the Secure access level, all settings, including the temperature, cannot be changed.

For more information, see the Miscellaneous (MISC) Menu section.

In the following menu tables, the access level the item is visible in is shown in the access column.

To adjust the Access Level:

1. Set the Unlock / Lock DIP switch to the unlock position. If a tN4 System Control is connected to the 162, the Unlock / Lock DIP switch on the tN4 System Control must be set to the unlock position.

2. Use the Menu button to select the MISC menu.

3. Use the Item button to select the Access item.

4. Use the Up and Down button to select the required Access Level.

User Interface

•

Use the User Interface available on the Liquid Crystal Display (LCD) to setup and monitor the operation of the setpoint control. Use the four push buttons below the LCD (Menu, Item, Up, Down) to select settings. As the settings are entered, record the settings in the Job Record J 162.

The menus display in the Menu Field at the left of the LCD.

Up to 6 menus are available:

• VIEW

• ADJUST

• SCENE

• SCHD (Schedule)

• MISC (Miscellaneous)

To select a menu, press and release the Menu button.

Item

In each menu, a group of items can be selected. The abbreviated name of the selected item displays in the Item field of the LCD display.

• To view the next available item, press and release the Item button.

• To view the previous item, hold down the Item button and press and release the Up button.

Adjusting a Setting

To adjust a setting:

1. Use the Menu button to select the appropriate menu.

2. Use the Item button to select a menu item.

3. Use the Up or Down button to adjust the setting.

Application Overview

The Setpoint Control 162 is designed to support six different applications. The items shown in the VIEW and ADJUST Menu change depending on the Application Mode.

Set the application mode as follows:

1) On / Off Setpoint

2) Hot Tub

3) Indirect DHW Tank

4) PWM Setpoint

5) Floor

6) Pool

Applications: On / Off Differential

Mode 1 Setpoint (On / Off)

Load

The VIEW and ADJUST menus list which of the six application items are visible based upon the mode column.

The TIME, SCHD (Schedule) and MISC (Miscellaneous) menus are the same for the six application modes.

Relay 1 On / Off Differential Operation

The On / Off Differential operates by centering a differential range around the target setpoint temperature. On / Off differentials are best suited to heating or cooling loads that quickly change temperature.

Heating Operation

When heating, the setpoint control turns on Relay 1 when the temperature falls to 1/2 of the differential below the setpoint and turns off Relay 1 once the temperature reaches 1/2 of the differential above the setpoint.

Mode 2 Hot Tub

Cooling Operation

When cooling, the setpoint control turns on Relay 1 when the temperature rises to 1/2 of the differential above the setpoint and turns off Relay 1 once the temperature falls 1/2 of the differential below the setpoint.

Applications: Pulse Width Modulation

Mode 4 Setpoint (PWM)

Load

Relay 1 Pulse Width Modulation (PWM) Operation

PWM operates by centering the throttling range around the target setpoint temperature. PWM is best suited for large heating or cooling loads that do not change rapidly in temperature. The Differential setting in the ADJUST menu changes the throttling range while in Application Mode 4 (Setpoint). The throttling range is not adjustable in Application Modes 5 (Floor) or 6 (Pool).

Heating Operation

When the temperature is at the setpoint, Relay 1 is on for 50% of a cycle and off for 50% of a cycle. When the temperature is 1/2 of the throttling range below the setpoint, Relay 1 is on for 100% of a cycle. When the temperature is 1/2 of the throttling range above the setpoint, Relay 1 is off for 100% of a cycle. For ranges within the throttling range, Relay 1’s on time increases linearly as temperature falls.

When the temperature is 1/2 of the throttling range above the setpoint, Relay 1 is on for 100% of a cycle. For ranges within the throttling range, Relay 1’s on time increases linearly as temperature rises.
