Kit HONEYWELL ElitePRO S1200 + Room Sensor YTHX1200W5/U | Montreal, Laval, Longueuil, South Shore & North Shore

The Honeywell ElitePRO S1200 kit with YTHX1200W5/U room sensor brings together in one box the most complete thermostat in the ElitePRO line, in white, and a RedLINK 3.0 wireless room sensor. It is the turnkey solution for homes where one room does not keep up with the others: the sensor is ready to install from day one, and the thermostat can immediately prioritize the occupied room instead of relying only on the temperature measured in the hallway.

A thermostat and its sensor, ready to work together

Temperature differences between rooms are common in Québec homes: a bedroom above an unheated garage, a corner room exposed to the prevailing winds, a finished basement, an office added during an extension. With a single measuring point on the wall, the thermostat has no way of knowing that the back bedroom is cold. The RedLINK 3.0 sensor included in this kit changes that: it wirelessly transmits the conditions in the room where it is placed, and the S1200 can adjust your furnace or central heat pump accordingly.

Additional C7189R3010-2 room sensors can be added later, as well as a C7089R3013 outdoor sensor and the EIM4010 interface module.

Where to place the sensor

The choice of location is critical. We recommend the room where comfort matters most and where the difference is greatest: often the primary bedroom for winter nights, or the family room for evenings. The sensor should be placed away from sunny windows, supply registers, electronic devices that give off heat and very cold exterior walls. Our technicians discuss it with you and install it in the right spot.

The included thermostat: the ElitePRO S1200

The thermostat in the kit is the white S1200, with a customizable 5 in. colour touchscreen that displays in French, English or Spanish. It streams live video from First Alert and Ring doorbells. It measures humidity, VOCs and estimated CO2, senses occupancy for Smart Away mode and controls up to two air quality devices (humidifier, dehumidifier, air exchanger or ventilation) through configurable outputs.

For connectivity, it uses dual-band 2.4/5 GHz Wi-Fi, RedLINK 3.0 and Matter, and works with Google Home, Amazon Alexa and Apple Home. The First Alert app offers remote control, schedules, energy use alerts, filter reminders and air quality notifications. It is compatible with demand response programs.

Compatibility with your system

The S1200 controls 24 VAC gas, oil or electric forced-air systems, hydronic systems, fan coils, PTAC units, dual energy and radiant systems. With a heat pump, it handles 3 heating stages and 2 cooling stages, up to 4 heating stages with the U/L terminals or an EIM. With a conventional system, it supports multiple stages; our technicians confirm the exact configuration based on your equipment. It does not control 120/240 V electric baseboards.

What the sensor changes in winter

Without a sensor, it is tempting to turn up the setpoint to warm the cold room, which overheats the rest of the house. With room priority, the system heats based on the room that matters at the time that matters. Combined with Smart Away and schedules, this avoids heating empty spaces. According to the manufacturer, the S1200 has earned ENERGY STAR certification.

Installing the kit

The thermostat requires a hardwired 20 to 30 VAC power supply with a common wire (C wire). The kit includes the white S1200 thermostat, the RedLINK 3.0 room sensor, the UWP wall plate, the cover plate and the hardware. Installation by AirGreen includes:

1. Checking the wiring and adding the C wire if needed.
2. Installing the thermostat and configuring the stages and dual energy.
3. Positioning and pairing the RedLINK sensor in the chosen room.
4. Setting room priority and schedules with you.
5. Connecting to Wi-Fi, the app and, if needed, your smart home platform.

Kit or thermostat alone

The white S1200 is available on its own (THX1200W5/U), without a sensor. The kit with sensor is the obvious choice as soon as you know a room is a comfort challenge. Another kit pairs the S1200 with the EIM4010 interface module instead of the sensor. We help you choose the combination that fits your home.

Maintenance

Clean the thermostat and the sensor with a soft, dry cloth. Do not move the sensor near a heat source, which would throw off the priority. Follow the filter reminders and have your system serviced every year.
