telkonet Energy Management System Controller

Overview

INTENDED AUDIENCE

These instructions are intended for:

Installers who are either Telkonet certified installers or have completed a series of Telkonet micro-training courses (contact your Telkonet Project Manager for details)
Facilities engineers who will maintain Telkonet devices.

WHAT IS ES CONTROLLER?

The ES Controller is an HVAC controller. You will wire it to the HVAC system. It does not have a user screen or any buttons for an occupant to press. The screen and the buttons are on a separate user interface. The controller and user interface communicate with each other wirelessly. Telkonet thermostats are “smart”. They are typically part of a larger energy management network. We call our thermostats the “brain of the room” because they gather data about the room (like occupancy status) and send it to a central location (usually Rhapsody).

WHAT CAN THE TELKONET THERMOSTAT DO?

The Telkonet thermostat will automatically learn and adapt to the heating and cooling patterns of each room.
For example, a room on the east side of a building will receive direct sunlight in the morning and will either need less heating or more cooling. However, as the day progresses, the room will need more heating or less cooling as it moves into the shade. A Telkonet thermostat will continually monitor the room, learn its patterns, and adjust its heating and cooling profiles accordingly.
Telkonet thermostats also learn and adapt to occupant schedules. When a room is unoccupied, the thermostat will enter an energy-saving mode, allowing the room to drift away from the desired set point. During this drift period, the thermostat will operate the HVAC unit less often, reducing energy costs. When the room becomes occupied again, the Telkonet Recovery Time™ technology built into each thermostat will return the room to the setpoint without the occupant noticing.

SAMPLE USE CASES

Telkonet thermostats are available in several possible configurations, to address specific requirements of multiple applications including hotels, classrooms, university housing, military residence halls, senior living facilities, multi-dwelling units, and a wide variety of other commercial and industrial spaces.

ABOUT WIRING THE ES CONTROLLER

The ES Controller interconnects with the existing HVAC system via standard wiring conventions, using 24-277 V ac OR 24 V dc voltage supplied by the HVAC system itself.
NOTE: The ES Controller allows for three different control voltages. Telkonet provides bare wire leads on all connectors. It is up to the installer to connect these leads using an appropriate method described herein. Wiring conventions follow industry standards; however, it is important to note that the relay configuration is dynamic and can be modified at the factory or in the field. It is important to always follow site-specific wire diagrams.

NTC PROBE

ES Controller has two inputs. Temp probes can be used for multiple purposes:

HVAC Discharge Air temp
HVAC Return Air temp
Supply Water Temp
Aqua Stat Mode (switches thermostat’s Heat/Cool) For temperature probe if not using Telkonet provided external temperature probe, a probe with a Beta R0 must match. Alternatively, a probe can be provided to Telkonet for lab calibration. Required specifications:

US Sensor model USP10972 or equivalent, per the following:

Resistance at 25 degrees C = 10 000 ohms +/- 1%
Resistance/Temperature curve = “J”
Beta ( 0 to 50 degrees C ) = 3892 degrees K nominal Other models may be compatible; provide model number and specifications. Other models may be compatible; provide model number and specifications.

CT INPUTS

All Models have 2 inputs. The CT inputs are commonly used for monitoring/alerting on fan motors, compressors or other equipment with excessive load or for determining a failure. The CT Inputs must be used with a compatible CT and sized appropriately for the load they will be connected to.
