Multi-Room Wireless Heating Solution – 50% Labor Savings, No Rewiring

Overview

Wired multi‑zone is costly and disruptive – wireless makes retrofitting simple.

Traditional wired systems require individual thermostats and dedicated cabling per zone, driving up labor costs and damaging walls and floors. For occupied homes or businesses, such upgrades are often impractical.

The SAS936FHL Wireless Kit changes that. One transmitter controls up to 8 receivers – each wired directly into existing heating loads. No new cables, no wall chases. Installation time cut by over half, with flexible independent zone control.

Core Capabilities

● Boiler On‑Demand Interlock
● One‑to‑8 control
● No rewiring
● 50% labor savings
● Weekly scheduling

Architecture Highlights

● Transmitter‑Receiver: Commands sent wirelessly, executed locally – no control cables.

● Star Topology: One transmitter manages up to 8 distributed receivers.

● Local Storage: Each receiver stores its own 7‑day schedule, retains through power loss.

Application Scenarios

Whole‑Home Retrofit - Zone comfort, whole‑home savings

Challenge: Different rooms have different heating needs. Traditional rewiring is costly, damaging, and disruptive to daily life.

Our solution: Transmitter in hallway, receivers connected to existing loads per room. Each room runs its own daily schedule – warm bedrooms at night, comfortable study by day, unoccupied rooms at reduced temps.

● Wireless control

● 7‑day scheduling

● Dual sensors

Office / Retail Zone Management – Heating on demand, zone by zone

Challenge: Workstations, meeting rooms, storage, and display areas have very different usage patterns. Wired upgrades disrupt business.

Our solution: Transmitter in management area, each receiver programmed independently – meeting rooms pre‑heated before use, storage at base temp, display areas comfortable all day. All zones monitored from one interface.

● Zone independence

● Weekly scheduling

● Energy management
