Introduction

This document provides information on installing the OpenBAS-HV-WLSTH wireless 
thermostat transmitter.

1.1

OpenBAS-HV-WLSTH Wired and Wireless Thermostat 
Transmitter

Mircom’s OpenBAS-HV-WLSTH wireless temperature and humidity transmitter and 
thermostat works with the OpenBAS-HV-VAVFC receiver controller to provide an easy-to-set-
up HVAC control for HVAC end unit applications such as: variable air volume (VAV) boxes, fan 
and coil units, mini split and water source chiller and heat pump units.

The OpenBAS-HV-WLSTH also connects to the receiver module OpenBAS-HV-RF433R to 
communicate with any OpenBAS-HV-NX10 series controller.

The OpenBAS-HV-WLSTH works in the 433 MHz unlicensed band to provide an RF link with a 
matched receiver up to 30 meters in line of sight applications and 15 meters indoors.

When used in wireless applications, it is powered by two AA alkaline batteries which provide 
between 12 and 18 months of operation, depending on the transmission rate.

It also comes standard with an integrated RS-485 port supporting multiple protocols. 

It can be integrated into any network and used as a standard temperature and humidity 
transmitter or as a powerful yet easy to set environment HVAC controller.

It is fully addressable, and when used wirelessly it can be programmed into a group out of 10, 
and each group can have up to 199 individual addresses.

When used wired it can be given an address between 1 and 199 depending on the protocol.

Features

The OpenBAS-HV-WLSTH integrates into Mircom’s unified platform for automating HVAC and 
mechanical rooms as well as incorporating energy management features and lighting control 
to offer building owners and managers a seamless operation with the following features:

Modular design to cover small, medium or large projects.

Industry standard field bus protocols to integrate into any existing BAS system, such as 
BACnet, Modbus, Optomux, N2-Open, and ASCII.

Connects to the NWK-ETH3 controller for integration into IP networks and uses the 
most advanced features and protocols such as distributed computing, USB and Cloud 
storage, HTML5, JavaScript, XML, Ajax, SMS, and GSM.

Modular add-ons for every Building Automation System solution.

The OpenBAS software which provides owners and managers a single solution for 
managing all their building’s automation needs.
