INTRODUCTION
The Novar ES3.S functions as an executive control module in Novar Opus Magnum building control supervisor, this Pop-
Off Pop-On design fits into XCM.10S and Savvy base-plate to provide easy migration. This document provides
instructions for installing the Novar ES3.S Executive Controller into an existing base-plate, and checking the installation.
Fig. 1. Novar ES3.S electronics assembly and bottom cover plate are included. XCM.10S and Savvy Base-plate is
currently a piece installed on site and is fully compatible with the new system (separate piece).
PRECAUTIONS
Take the following precautions during installation:
OBSERVE NATIONAL AND LOCAL ELECTRICAL CODES.
• Reduce the risk of electrical shock or fire. Do not interconnect the outputs of different Class 2 circuits.
• Do not rely on the Novar ES3.S as a final safety device.
• Make sure that the 24-VAC power wiring is connected to a dedicated transformer. No other devices (including
the outputs) should be powered by the transformer connected to the Novar ES3.S
• Do not ground the transformer for this module on the secondary side.
• Make sure that the Novar ES3.S power cannot be switched off accidentally. The Novar ES3.S requires
continuous power for proper operation.
If the Novar ES3.S has been provided as a replacement for an xcm.10S and Savvy Controller, the instructions in
this document for wiring a Digital Outdoor Light Sensor (OLS) and/or an Outdoor Temperature Sensor (OTS) to
the Novar ES3.S must be followed carefully. See “Wiring” on page 4.
