Example: With Humidify at 55% and a Variance of 5%, a call for

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.

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.

following controls:

MANUAL RELAY OPERATION (K/H/D AND K2)

When set to 'Manual', the relay can be turned on or off using any

of the remote connection options.

Accessory port

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
