Programming and Configuration of Thermostats

2

WebStat Programming/Configuration

• Login using a Contractor level user ID and password

3


• From the Overview screen, click on the “Thermostats” tab

4

Thermostat Discovery

• Thermostats already on the network will show up• Click the “Discover” Button to discover new thermostats

- If there are any existing thermostats, you’ll see a warning stating that any devices with subnet/node conflicts will be re-commissioned.

5

Thermostat Discovery

• A status window will appear• When complete, the Thermostats screen will appear with

all of the discovered thermostats

6


• Discovered thermostats are listed and a status of “Online” shows for all discovered thermostats

• The “Last Updated” column will read “Download Pending”• Click on the “Edit” button of a thermostat to begin

configuration

7


• WebStat uses a wizard to configure the thermostats so it is not necessary to interface directly with the thermostat

• All configuration parameters are chosen from a list of pull down menus in 7 different screens- Properties

- Inputs

- Cooling Configuration

- Heating Configuration

- Outputs

- Setpoints

- Dehumidification

• WebStat also provides customized wiring diagrams for every thermostat configured

8

Properties• Thermostat name

- Add a meaningful thermostat name

• Choose the model- T7350H1009 for staged and T7350H1017 for modulating

• Equipment type- Conventional or Heat Pump

• Neuron ID- Already filled in via the auto discovery

• Keypad lockout- Choose to lockout keys on the thermostat

• System mode- Auto, Off, Cool or Heat

• Fan Switch- On or Auto

• Override duration- Choose from 1 to 8 hours for the override duration

• Transformers- Use only for wiring diagram purposes

9

Inputs• Room temperature input

- Choose local to use the on board sensor, select from different remote sensors or choose to network to get temperature from another T7350 If a remote sensor is selected, choose the number of remote sensors if averaging is

desired and a wiring diagram will be created detailing the correct wiring for sensors

• Relative humidity input- Choose local for the on board sensor, remote for a remote sensor or

network to get relative humidity from another T7350

• Outdoor temperature input- Choose remote if an outdoor air sensor is connected to this thermostat, or

choose network if another T7350 has the outdoor air sensor

• Occupancy sensor input- Choose none, remote or network for an occupancy sensor

• Discharge air temperature input- Choose none or remote

10

Cooling Configuration• Stages required

- Choose 1 to 4 stages of cooling To choose 4 stages of cooling, heating stages must be set to 2 or fewer

• Extended fan- You may extend the fan run time after the compressor shuts down by 40

seconds if desired

• Cycle rate- Choose 3 or 4 cycles per hour (cph)

• Advanced settings- Cooling OAT lockout

Pick an outdoor temperature at which to lock out cooling

- Cooling DAT lockout Pick a discharge air temperature at which to begin shutting down stages of cooling

11

Heating Configuration• Stages required

- Choose 1 to 3 stages of heating If 4 stages of cooling has been chosen, only 2 stages of heat are available

• Fan operation- Choose ON With Heat to turn the fan on immediately with a call for heat

- Choose OFF With Heat to let the equipment turn on the fan

• Extended fan- You may extend the fan run time after the heat shuts down by 90 seconds

if desired

• Cycle rate- Choose 3, 6, 9 or 20 cycles per hour (cph)

• Advanced settings- Heating OAT lockout

Pick an outdoor temperature at which to lock out heating

- Heating DAT lockout Pick a discharge air temperature at which to begin shutting down stages of heating

12

Outputs• Auxiliary output logic

- Time of Day (TOD) Output will energize during Occupied and de-energize during Unoccupied

- Economizer Same as TOD but will energize during Unoccupied on a call for cooling

- Simple Dehumid Output will close whenever humidity is higher than the high limit

• There is a 5 minuet minimum on timer and a 5% hysteresis for dehumidification

- Hot Gas Bypass Same as simple dehumid, but will not energize if a stage of cooling is on

• Reversing valve- Only for heat pumps, choose active on heating or cooling

• Advanced- Gives access to the PID control loop

Strongly recommended that these settings not be changed

13

Setpoints• Choose setpoints for Occupied, Unoccupied and Standby

- There is a minimum deadband of 2°F

- The heating setpoint must be lower than the cooling setpoint

• Advanced- Maximum and minimum stops can be set for heating and cooling

setpoints

- Recovery ramp rates for heating and cooling are set

14

Dehumidification• Dehumidification high limit

- This high limit may be changed via the keypad as well

• Minimum on time- Choose a minimum run time for the compressor when the humidity is

above the high limit

• Reheat- When humidity is above the high limit, the first stage of heating and

cooling will run at the same time

• Reset temperature setpoint- Choose to lower the cooling setpoint when humidity is above the high

limit

15

Wiring

• A list of terminal designations is provided• Click on View Wiring to see a wiring diagram• Click on View Sensor to see a sensor wiring diagram

- Only shown for thermostats with sensor averaging

16

Wiring

• Custom wiring diagrams for each thermostat configured

Subbase wiring

Remote sensor averaging wiring

17

Wiring

• Clicking the “Finish” button will bring you back to the Thermostats page

• Click on the “Schedules” tab to begin creating schedules

18

Schedules

• Existing Schedules will show in the left column• Click on “New Schedule” to create a new schedule

19

Schedules

• Type a name for the new schedule• Schedule events by clicking on endpoints and stretching

or shrinking the event• To shift events, hold down on the Shift key and drag

20

Schedules

• To change the type of event, click on the event and then choose Occupied, Unoccupied or Standby

• To delete an event, click on the event and click “Delete Event”

21

Special Events

• Choose a name for the new holiday• Choose Date, Date Range or Day and Week• Select the date(s) and choose Occupied or Unoccupied as

well as a start and end time of day for the event

22

Special Events

• Click the “Assign Thermostats” tab to assign thermostats to the newly created schedule

• Highlight the thermostat(s) and click the right arrow button to assign the thermostat to the schedule

23

Schedules

• Assigned thermostats will now show on the schedules tab
