dehumidification would start at 60% and turn off when the  

humidity level drops to 50%.  

INTRODUCTION  

ACCESSORY PORT  

This addendum addresses the special controls available using  

the K/H/D and K2 terminals on the X7 Series thermostats. This  

includes control of humidity, fresh air damper, 7-day / 4-event  

relay scheduling, manual relay operation, and Indoor Air  

Quality (IAQ) Control  

The accessory port allows the connection of various NetX  

options, including the NT-MOD-ULE wireless sensor  

coordinator, the NT-CO2 carbon dioxide sensor, or other future  

accessories.  

FRESH AIR DAMPER OPERATION (K/H/D OR K2)  

When set to 'Damper', the relay will control a 2-position (power  

open, spring return) damper for fresh air ventilation.  

NetX™ X7 Series  

Thermostat  

K/H/D RELAY - GENERAL  

The K/H/D relay can be configured to function as any one of  

the following controls:  

The ‘When Occupied’ setting will open the damper and turn on  

the fan during occupied schedule periods from the thermostat’s  

normal 7-day schedule.  

K/H/D & K2 INSTALLATION ADDENDUM  

The ‘x min/hr’ setting will open the damper and turn on the fan  

for the set number of minutes selected. Outdoor Temperature  

and Humidity Limits allow the setting of the boundaries for  

energizing the damper, between 120°F (49°C) and -40°F (-40°C),  

and 0% RH to 100% RH.

When set to 'Humidification', this feature allows the selection  

of a humidification call only when the heat is running, or  

independent of a heating call.  

Integrated HVAC - Occupied  

Use when IAQ equipment is located inside the HVAC equipment  

or ductwork. This setting will turn on the IAQ equipment and the  

HVAC fan during occupied schedule periods from the  

thermostat’s normal 7-day schedules.  

The relay energizes a humidification call when the indoor  

relative humidity drops below the value selected, with a  

programmable variance of ± 2%, 3%, or 5% RH.  

Stand Alone - Occupied  

Example: With Humidify at 35% and a Variance of 5%, a call for  

humidification would start at 30% and turn off when the  

humidity level reached 40%  

Use when IAQ equipment is located inside the HVAC equipment  

or ductwork. This setting will turn on the IAQ equipment during  

occupied schedule periods from the thermostat’s normal 7-day  

schedules.  

Dehumidification:  

CO2 Introduction  

When set to 'Dehumidification', this feature allows the  

selection of a dehumidification call only when the cooling is  

running, or independent of a cooling call.  

Integrated HVAC - Manual  

Access the Installer Menu  

Access the First CO2 Settings  

Setting the CO2 Display  

Setting the CO2 Alert Setting  

Clear CO2 Max Setting  

Use when IAQ equipment is located inside the HVAC equipment  

or ductwork. This setting will allow the manual turning on or off  

of the IAQ equipment and the HVAC fan. Use this setting for  

extended occupied or unoccupied periods.  

When "With Cooling Only" is selected, and there is no  

dedicated dehumidification function integrated within the  

equipment, cooling will be initiated and the cooling set point  

will automatically be lowered by 2 degrees from the scheduled  

cooling set point to allow increased equipment run time and  

decreased space humidity levels.  

Stand Alone - Manual  

Use when IAQ equipment is located inside the HVAC equipment  

or ductwork. This setting will allow the manual turning on or off  

of the IAQ equipment. Use this setting for extended occupied or  

unoccupied periods.  

BEFORE YOU START  

Please read the entire addendum. The thermostat will need  

to be correctly wired and configured for proper operation.  

Basic HVAC configuration can be performed from the  

thermostat touchscreen and advanced settings can be  

accessed on the embedded web pages and the Internet.  

The relay energizes a dehumidification call when the indoor  

relative humidity rises above the value selected, with a  

programmable variance of ± 2%, 3%, or 5% RH

• Page 2: This completes the CO2 settings that can be controlled from the Installer Menu. Additional advanced settings can be accessed on the embedded web pages and/or the Internet via our NetX CloudConnect software. By default, the CO2 Alert setting is set to trigger when the X7 thermostat detects a CO2 reading above 1100 ppm. When triggered, the alert can activate a relay to open a fresh air damper to decrease the level of CO2 in the control area. To adjust the alert level, use the Up and Down buttons. The level is changed in increments of 50 ppm, with a range from 500 ppm to 2000 ppm. This addendum addresses the installation and configuration of the CO2 sensor for the X7C and X7 Series thermostats. The default CO2 Display setting is On, meaning the CO2 setting will be visible on the upper left corner of the display when the thermostat is in normal mode. By default, the Clear CO2 Max setting is set to No, meaning the maximum recorded CO2 level will not reset until user intervention. This setting can be changed to reset automatically at 12 midnight or reset immediately.
