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).

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

Applications: Pulse Width Modulation

Mode 4 Setpoint (PWM)

Mode 5 Floor

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.

Sequence of Operation

Application Mode 1 - On / Off Setpoint SECTION A

Application Mode 1 is a generic setpoint control operation using an on/off differential for heating or cooling. The sensor is required to be located at the temperature control point. The setpoint control can have an occupied, unoccupied, and away temperature setting.

Relay 2 Operation

Relay 2 operates continuously while in the occupied period to provide constant circulation and reduce temperature swing.

Relay 2 operates together with Relay 1 while in the unoccupied and away periods.

Setting the Setpoint Off

The setpoint temperature can be set to Off. When set to Off, Relay 1 and 2 will not turn on. If the heating area is

Load

Relay 1 Operation

Relay 1 operates using an on/off differential to maintain the load at the Occupied, Unoccupied, or Away temperatures depending on the schedule and scene.

outdoors, or the heating system has the potential to freeze, it is recommended that the setpoint always be set to a temperature and not set to Off.

The setpoint can be set to Off if the heating system can be drained or the pump should remain off.

The setpoint control power should never be shut off, otherwise an error message will appear on the rest of the tN4 system.

Application Mode 2 - Hot Tub SECTION B

Application Mode 2 is designed specifically to heat hot tubs using an on/off differential. A sensor must be located in a temperature well on the recirculation pipe. The hot tub can have an occupied, unoccupied, and away temperature setting.

Hot Tub Filtration

The hot tub application includes special logic to operate the pump controlled by Relay 2. The Relay 2 Pump On setting in the Adjust menu allows installers to choose a time at which Relay 2 starts a pump for filtration of the hot tub. The Relay 2 Pump Run Time setting in the Adjust menu determines how long Relay 2 should run the pump for filtration.

The Hot Tub Filtration feature can only be used when a programmable setback schedule is set to Zone, Schedule Master, Schedule Member, or set to Unoccupied.

Relay 1 Operation

Relay 1 operates using an on/off differential to maintain the load at the Occupied, Unoccupied, or Away temperatures depending on the schedule and scene.

Relay 2 Operation

Relay 2 operates continuously while in the occupied period to provide constant circulation and reduce temperature swing.

Relay 2 operates together with Relay 1 while in the unoccupied and away periods.

Relay 2 can optionally operate to provide Hot Tub Filtration.

When connected to a tN4 system control, Relay 2 can optionally operate to provide temperature sampling of the hot tub.

Temperature Sampling

When the setpoint control is connected to a tN4 System and the hot tub pump operated by Relay 2 is off during the unoccupied and away periods, the setpoint sensor may not accurately read the hot tub temperature due to a lack of flow past the sensor. In order to accurately sample the hot tub temperature, the Relay 2 Sample setting can be set to On. Relay 2 then turns on the hot tub pump for approximately one minute at the end of each heating cycle to allow the control to accurately measure the hot tub temperature.

Mode of Operation

The hot tub mode of operation can be set to either Heat or Off. While set to Off, Relay 1 and Relay 2 remain off. The Off setting should only be used when the hot tub is drained or when there is no possibility of freezing. Power should never be removed from the setpoint control as this will result in an error message on the tN4 system.

Page 21

Occupied Time

The setpoint control can temporarily override the scheduled temperature and operate at the occupied temperature on a timer.

Press the Up or Down buttons while in the View menu to set the amount of time that the occupied temperature should remain in effect.

To use this feature, a programmable schedule must be set or the schedule be set to normally operate at the unoccupied setting. When the schedule is set to unoccupied, the setpoint control operates at the unoccupied setting until activated.

The length of time the setpoint remains at the occupied temperature is preset by the Run Time Occupied item located in the Scene menu.

To cancel the temporary occupied time, press and hold the Down button until the display shows OFF, at which point, the setpoint control returns to the schedule.

Pressing the UP button while in the VIEW menu starts operation of the Hot Tub for the time set. To Stop operation press the DOWN button until the time shows OFF.

Application Mode 3 - DHW Tank SECTION C

Application Mode 3 is designed specifically to operate a

The setpoint can be set to Off if the heating system can be drained or the pump should remain off.

The setpoint control power should never be shut off, otherwise an error message will appear on the rest of the tN4 system.

Page 22

Application Mode 5 - Floor SECTION E

Application Mode 5 configures the setpoint control for floor warming and floor heating applications using pulse width modulation. Floor warming is not necessarily designed to heat the room, but to make the floor feel warm to the touch. This is common especially in bathrooms. For bathroom applications, Relay 2 can also heat a towel warmer radiator while in the occupied period. A sensor must be located within the slab between the heating pipes. The setpoint control allows a Floor temperature to be set for the occupied, unoccupied, and away events.

Relay 1 Operation

Relay 1 operates using pulse width modulation to maintain the load at the Occupied, Unoccupied, or Away temperatures depending on the schedule and scene.

Occupied Time

The setpoint control can temporarily override the scheduled temperature and operate at the occupied temperature on a timer.

Press the Up or Down buttons while in the View menu to set the amount of time that the occupied temperature should remain in effect.

The length of time the setpoint remains at the occupied temperature is preset by the Run Time Occupied item located in the Scene menu.

To cancel the temporary occupied time, press and hold the Down button until the display shows off, at which point, the setpoint control returns to the schedule.

Relay 2 Operation

Relay 2 operates continuously while in the occupied period to heat a towel warmer.

Relay 2 remains off during the unoccupied and away periods.

Pressing the UP button while in the VIEW menu starts operation of the Hot Tub for the time set. To Stop operation press the DOWN button until the time shows OFF.

Application Mode 6 - Pool SECTION F

Application Mode 6 configures the setpoint control for pool heating using pulse width modulation. A sensor is located in a temperature well on the pool return recirculation pipe. The pool can have an occupied temperature. During the unoccupied and away periods, the pool is not heated.

Relay 2 Operation

Relay 2 operates continuously while in the occupied period to provide constant circulation and reduce temperature swing.

Relay 2 remains off during the unoccupied and away periods.

Relay 2 operates to provide pool filtration.

Pool Filtration

The pool application includes filtration logic to operate the pump controlled by Relay 2. The Relay 2 Pump On setting allows installers to choose a time at which Relay 2 starts a pump for filtration of the pool. The Relay 2 Pump Run Time setting determines how long Relay 2 should run the pump for filtration.

Relay 1 Operation

Relay 1 operates using pulse width modulation to maintain the load at the occupied temperature. Relay 1 remains off during the unoccupied and away periods.

Mode of Operation

The pool mode of operation can be set to either Heat or Off. While set to Off, Relay 1 and Relay 2 remain off. The OFF setting should only be used when the pool is drained or there is no possibility of freezing. Power should never be removed from the setpoint control as this will result in an error message on the tN4 system.

Page 23

Cycle Length SECTION G

Select the heating or cooling cycle length in minutes for Application Modes 4 (Setpoint), 5 (Floor), and 6 (Pool). The cycle length is the total on time and off time of Relay 1. This helps prevent short cycling. The following settings are available:

CTRL = The cycle length is the same as the tN4 system

control. This is the factory default.

SYNC = The cycle length synchronizes with other ther-

mostats and setpoint controls that have also been set to the SYNC setting.

5 to 30 minutes = The cycle length is manually set.

Note: The factory default changes to synchronize (SYNC)

when a tN4 control is not present. The factory default changes to 15 minutes when the mode of operation is set to Cool.

Relay Minimum On and Off Time SECTION H

Relays 1 and 2 have adjustable Minimum On and Minimum Off time settings available in the Adjust menu only with Application Modes 1, 2, and 3 (using on-off differential).

These settings help prevent short cycling of the relays and the heating or cooling equipment.

Remote Enable / Disable SECTION I

To use the Remote Enable / Disable feature, the setpoint control must be set to Mode 1 (Setpoint), 2 (Hot Tub), 4 (Setpoint), or 5 (Floor). When the setpoint control is connected to a tN4 system, a User Switch or tN4 Gateway can remotely signal a setpoint control (or multiple setpoint controls) to override the unoccupied temperature to temporarily operate at the occupied temperature. The Setpoint Control, User Switch and tN4 Gateway each have a setting called Setpoint Device Enable that can be assigned a number between 1 and 12. When devices have the same Setpoint Device Enable number, then either pressing the button on the User Switch or activating the feature on the tN4 Gateway causes the Setpoint Control to operate at the occupied temperature. Sending a second Setpoint Device Enable cancels the override and the setpoint control returns to the unoccupied temperature. A total of 12 different Setpoint Devices Enables can be configured on the tN4 system.

To create a Setpoint Device Enable:

1) DIP switch 2 must be set to tN4 system control.

2) A User Switch or tN4 Gateway should be connected to one of the tN4 buses.

3) Set the Setpoint Device Enable item in the Adjust menu to a number between 1 and 12.

4) Set the Setpoint Device Enable on the User Switch or tN4 Gateway to the same number between 1 and 12.

The schedule on the setpoint control must be set to either Zone, Schedule Master, Schedule Member, or to Unoccupied to allow the temporary occupied time override to operate. Wh en t he s chedule is set to Unoccup ied, the s etpo int cont rol operates at the unoccupied setting until activated.

The length of time the setpoint remains at the occupied temperature is preset by the Run Time Occupied item located in the Scene menu.

Remote activation of the setpoint control requires the same Se tpoin t Dev ice en able n umbe r to b e set on th e se tpoin t cont rol and on a User Switch 480 or 481 (or tN4 Gateway).

Sensor Input SECTION J

•

• •

•

The Setpoint Control 162 requires a temperature sensor (Universal Sensor 071 included) to be connected to the sensor input on the back of the control. All tekmar sensors

are compatible. Choose the sensor type that best meets the requirements of the application. See application mode diagrams for the recommended location of the sensor.

Time Clock SECTION K

• Use the Time menu to set the correct time.

The setpoint control has a built-in time clock to allow the control to operate on a programmable schedule. A battery less backup allows the control to keep time for at least 4 hours without power.

Setting the Schedule SECTION L

To provide greater energy savings, the setpoint control can operate on a programmable schedule. The schedule is stored in memory and is not affected by loss of power to the control. A single zone or multiple devices on the tN4 system can be assigned to follow the schedule of the setpoint control.

Zone Schedule

A zone schedule only applies to the setpoint control on which the schedule is programmed. The setpoint control follows the zone schedule and the events are not communicated to other devices on the tN4 system.

Master Schedule

If the setpoint control is connected to other devices on the tN4 system, then the setpoint control can operate on a master schedule. The master schedule stores the event times in memory and sends messages to the member thermostats when to change from one event to the next.

A maximum of four master schedules can be set up on the tN4 system. A master schedule is available to all devices on the tN4 system. Master schedules simplify installation by allowing one master schedule to be used by multiple devices.

Schedule Member

If a Master Schedule is available on the tN4 system, the setpoint control can follow the Master Schedule as a member.

To follow a master schedule as a member:

1. Assign the setpoint control to follow a master schedule by setting the Schedule menu item in the Schedule menu to Member (MBR) 1 to 4. The number must match that of the Master.

Normally Unoccupied

The setpoint control can be set to normally operate at the unoccupied temperature. This allows the setpoint control to temporarily be set to the occupied temperature by either pressing the Up or Down buttons in the View menu or by a remote enable.

Schedule Types

The schedule type determines when the schedule repeats itself.

The setpoint control includes four schedule types:

• 24 Hour: Repeats every 24 hours.

• 5-2: Repeats on a weekly basis. However, it breaks the

week into the weekend and weekdays. This reduces the amount of schedule event settings.

• 5-11: Repeats on a weekly basis. However, it breaks the week into Saturday and Sunday followed by the weekdays. This reduces the amount of schedule event settings.

• 7 Day: Repeats on a weekly basis and allows for separate event times for each day.

To create a master schedule:

1. Assign the setpoint control as a master schedule by setting the Schedule item in the Schedule menu to

Master (MST) 1 to 4.

If the setpoint control is a master schedule, a clock symbol appears in the display while in the View menu. This helps locate the master schedule if changes to the schedule are required.

Scenes SECTION M

A Scene function is available on the setpoint control.

• To use the scene function, go to the Scene menu and set the Scene setting to On.

Scenes are overrides that affect devices on the tN4 system. Scenes provide a method of changing the temperature throughout an entire building from a single tN4 device. Each tN4 device is programmed to operate at either at a temperature (Occupied, Unoccupied, Away) or follow the regular setback schedule. If a programmable schedule is not used, only the occupied and away temperatures are available. A permanent scene remains in place until another scene is selected. When a temporary scene is selected (Scenes 6, 7, 8), a timer counts down and when it times out, devices return to the last permanent scene selected.

See the Scene table for details regarding the operation of Scenes. There are a total of eight Scenes available.

• Default Scene: The default scene is Permanent 1. In a typical installation, the setpoint control is set to follow

the schedule in the Permanent 1 scene.

• Factory Set Scenes: Scenes 2, 3 and 6 are factory set and force the setpoint control to the Away, Unoccupied

or the Occupied temperature respectively.

• Customized Scenes: Scenes 1, 4, 5, 7, and 8 can be customized to either follow the scheduled event, or the temperature can be forced to the Occupied, Unoccupied, or the Away temperature.

Away Hold SECTION N

•

To setback the temperature while the occupants are away, use the Permanent Away 2 scene. This scene changes all the devices on the tN4 system to the Away temperature setting.

To set the Away temperature, go to the Adjust menu and select the Setpoint (or Hot Tub, DHW, Floor) Away item. When operating a pool, the away scene no longer heats the pool. The Access Level must be set to User, Installer or Advanced.

The Away Hold feature allows you to set the number of days the Away temperature applies.

To set the number of days away, go to the Scene menu and select Away Hold.

When set to Infinite, the Away 2 scene remains until a new scene is selected. If it is known in advance how long the building occupant will be away, the Away Hold can be

set to the number of days. Once the number of days have elapsed, the thermostat automatically changes from the Away 2 scene to the previous permanent scene.

Example:

The home occupants are traveling for 14 days. The occupants want the home to be at the Away

temperatures for 14 days and then automatically return to the normal schedule.

• Locate the Scene Menu.

• Set the Away Hold to 14 days.

tN4 Features SECTION R

When the setpoint control is connected to a tN4 system, the setpoint control has additional features not present when operating alone.

tN4 Bus

When connecting the setpoint control to a tN4 system, there may be several tN4 busses available. The setpoint control should be connected to the tN4 bus that best represents the water temperature required for the setpoint load. Typically, the setpoint control should be connected to the boiler tN4 bus for Application Modes 2 (Hot Tub) and 3 (DHW Tank). Typically the setpoint control should be connected to a mix tN4 bus for Application Mode 5 (Floor).

Heat Source

When the setpoint control is part of a tN4 system, the Heat Source item in the Adjust menu a llows the setpoint control to inform the tN4 system control whether the heat is hydronic (HYDr) or provided by another (OTHr) heat source.

Exchange Supply

When the setpoint control is connected to a tN4 system control and Heat Source item is set to hydronic (HYDr), the setpoint control requests that the Exchange Supply Occupied water temperature be maintained on the tN4 bus whenever Relay 1 is heating the setpoint load during

Page 27

the occupied period. During the unoccupied periods, the exchange supply water temperature is lowered by the difference between the occupied and unoccupied setpoints. During the away period, the exchange supply is lowered by the difference between the occupied and the away setpoints.

Maximum Supply

When the setpoint control is connected to a tN4 system control and the Heat Source item is set to hydronic (HYDr), the setpoint control requests an Exchange Supply water temperature on the tN4 bus. The setpoint control also includes a Maximum Supply setting. Should the water temperature on the tN4 bus exceed this water temperature, then the setpoint control discontinues heating by shutting off Relay 1.

and Relay 1 is turned on, the “system” pump waits for 3 minutes before turning on.

When the setpoint control is connected to the tN4 boiler bus, the “system” pump is the primary pump located on the tN4 system control.

When the setpoint control is connected to a tN4 mix bus, the “system” pump is the mix system pump located on the tN4 system control or on a mixing expansion module.

Purging

When the setpoint control is used with a tN4 system control, the setpoint control purges heat from the boiler into the setpoint zone if it is the last zone to shut off. The length of the purge is dependent on time, the temperature of the boiler, and the temperature of the setpoint load.

Relay 1 System Pump

In order to accommodate many different piping and pumping configurations, the setpoint control is able to choose whether a “system” pump is required to operate at the same time as Relay 1. This allows each manifold on a water temperature to have a “system” pump when using zone valves or when using zone pumps together with primary secondary piping. Only the manifold that has zones requiring heat should have their “system” pump turned on.

When the setpoint control is connected to the tN4 boiler bus, the “system” pump is the primary pump located on the tN4 system control.

When the setpoint control is connected to a tN4 mix bus, the “system” pump is the mix system pump located on the tN4 system control or on a mixing expansion module.

To turn on the “system” pump together with Relay 1, set the Relay 1 Pump item in the Adjust menu to On. This is the factory default.

To turn on Relay 1 without the “system” pump, set the Relay 1 Pump item in the Adjust menu to Off.

Relay 1 Delay System Pump

In applications where a thermal motor zone valve (telestat) is operated by Relay 1, a time delay is required to allow the zone valve to fully open before the “system” pump is turned on. The time delay is set using the Relay 1 Delay item in the Adjust menu. When the time delay is set to On

Priority

When the setpoint control is used with a tN4 system control, the setpoint control has up to 5 levels of priority when connected to a tN4 boiler bus and 2 levels of priority when connected to a tN4 mixing bus. Devices are shut off in order of their tN4 address, with address ending in 24 having the lowest priority and addresses ending in 01 having the highest priority. See “tN4 Address” for more information.

Locate the Priority item in the Adjust menu. When the setpoint control is connected to a tN4 boiler bus,

the priorities are as follows: STAT = Thermostats have priority over the setpoint control.

The setpoint control no longer heats whenever any

thermostat calls for heat. OFF = All devices have equal priority. LO = The setpoint control has priority over the ther-

mostats. First, all mixing outputs are reduced.

Second, boiler temperature second stage heating

zones are shut off in order of their tN4 address

from 24 to 1. Last, boiler temperature thermostat

zones are shut off in order of their tN4 address

from 24 to 1. MED = The setpoint control has priority over the thermo-

stats. First, all heating zones are shut off. If there

is sufficient boiler capacity, boiler temperatures

zones are turned on in order of their tN4 address

from 1 to 24. Second, boiler temperature second

stage heating zones are turned on in order of their

tN4 address from 1 to 24. Last, all mixing outputs

are increased up to normal operating levels. HI = All thermostat heating zones are shut off whenever

the setpoint control calls for heat. When the setpoint control is connected to a tN4 mix bus,

the priorities are as follows:

STAT = Thermostats have priority over the setpoint control.

The setpoint control no longer heats whenever any thermostat calls for heat.

OFF = All devices have equal priority.

Outdoor Temperature

•

The setpoint control can display the outdoor temperature in the View menu when connected to a tN4 bus with a device measuring the outdoor temperature. To display the outdoor temperature, set the Out item in the Adjust menu to On.

Warm Weather Shut Down

The Warm Weather Shut Down (WWSD) feature prevents the setpoint control from heating once the outdoor temperature exceeds the WWSD occupied or WWSD unoccupied setting.

In order to use the WWSD, the setpoint control must be connected to a tN4 bus with a device measuring the outdoor temperature.

• Locate the WWSD setting in the Adjust menu.

Cold Weather Shut Down

The Cold Weather Shut Down (WWSD) feature prevents the setpoint control from cooling once the outdoor temperature falls below the CWSD occupied or CWSD unoccupied setting.

In order to use the CWSD, the setpoint control must be connected to a tN4 bus with a device measuring the outdoor temperature.

• Locate the CWSD setting in the Adjust menu.

tN4 Address

When connected to other tN4 devices through a tN4 bus, the setpoint control is automatically assigned a network address. The Address item in the Miscellaneous menu displays the current address of the setpoint control. A total of 24 devices can be connected to each tN4 bus.

If the 162 is operating as a member of a thermostat / setpoint only network, the address consists of a device number with no bus number. If the 162 is not connected to a tN4 network, the address item in the MISC menu is not available.

When the setpoint control is connected to a tN4 boiler bus, the address range is b:01 through to b:24.

When the setpoint control is connected to the tN4 mix 1 bus, the address range is 1:01 through to 1:24.

When the setpoint control is connected to the tN4 mix 2 bus, the address range is 2:01 through to 2:24.

When the setpoint control is connected to the tN4 mix 3 bus, the address range is 3:01 through to 3:24.

The address number determines the heating priority for each zone. A device with address number 1 has a higher priority than address number 24. The tN4 address allows the tN4 system control to shut off low priority zones when the heat source is unable to heat all zones simultaneously. In some cases, the installer may want to change the device’s address in order to change the thermostat’s priority relative to other devices.

Note: Keep track of manually set tN4 addresses. When a tN4 address is manually set, tN4 devices using the Auto address setting will automatically be assigned new addresses. If two devices are manually set to the same address, an error message will appear. The error remains until one of the addresses is manually changed to a vacant address.

Zone Test

The tN4 system control has a Zone Test feature, which allows each tN4 device to be individually operated for up to 5 minutes. When the setpoint control is selected, the display shows “Zn TEST” and Relay 1 and Relay 2 are turned on. When the setpoint control is not selected, the display shows “Zn TEST” and Relay 1 and Relay 2 are turned off.

Maximum Heat

The tN4 system control has a Maximum Heat feature, which operates all tN4 devices, including the setpoint control, at the occupied temperature setting plus 5°F (3°C). While in the maximum heat operation, the setpoint control display shows the “MAX HEAT” symbols.

Exercising

When connected to a tN4 system control, the setpoint control exercises Relay 1 and Relay 2 for 10 seconds after 3 days of inactivity. Exercising helps prevent pump seizure. While the setpoint control is exercising, the display shows “TEST”.

Exercising does not occur when:

• Mode of Operation is set to Off.

• Heat Source is set to Other.

• DIP switch 2 is set to None.

Error Messages

Local Errors and Device Errors

Error messages are used to indicate a problem somewhere in the system. There are two types of error messages: Local Errors and Device Errors.

A Local Error indicates an error specific to a device. For example, a thermostat with a sensor short circuit will show a Sensor Short Error on its display. No other devices will show this specific error (unless they also have a sensor short circuit).

A Device Error is used to indicate that there is a local error somewhere else on the system. For example, if a thermostat has a sensor short circuit, that thermostat will show a Local Error indicating specifically what the problem is. All other devices on the network will show Device Errors, indicating the address of the device with the Local Error. In other words, Device Errors are nothing more than pointers, showing you that there is a local error somewhere on the system and where to find it.

Error Priority

Only one error can be shown on a particular device at a time. If there is more than one error on the system, the highest priority error will be the one that is shown. The table on pages 30 and 31 lists error messages in order of high priority to low priority.

How to Locate an Error Message

If the warning symbol (flashing circle with exclamation mark) is visible on screen, this indicates that there is an error somewhere on the system. To view the error message, you must first put the control into the Advanced or Installer access level (available in MISC menu). When an error message is present, it is available as an item in the VIEW menu.

While in the View Menu, press the item button until the error message is displayed. You may have to advance through several View Menu items before the message is displayed.

If the error message is a Device Error (if “DEV” or “DEV ERR” is shown on screen), read the address shown and go to the device with that address. That device will have a Local Error indicating specifically what the problem is. When the problem is corrected, the error message will automatically clear.

Access Levels

In some cases, it is not desirable to let day-to-day users view error messages. In these cases, by lowering the access level of the thermostat or setpoint device to ‘User’ or lower, error messages cannot be seen in the View menu and the warning symbol only appears if there is a local error or a device error caused by a critical error on another device. If there is an error message on the system that you cannot find on a particular thermostat, make sure that the access level on that thermostat is set to Installer or Advanced.

Sensor Temperature Errors

If a control is unable to display a temperature due to a sensor malfunction or communication problem, the word “Err” is displayed in place of the temperature. This usually indicates that there is an error somewhere on the system but is not the actual error message. Keep looking through the View menu to find the actual error message.

sensor problem.

Keep pressing the Item button to find the actual

error message
