MCO Home Water Heating Thermostat with humidity sensor Version 2

The MCO Home Water Heating Thermostat with Humidity Sensor, Version 2 (model likely MH7H-WH2), is a Z-Wave Plus smart thermostat specifically designed for hydronic (water-based) heating systems.

Here are the key features and specifications:

Functionalities:

• Application: Primarily for controlling water-based heating systems, such as:

  • Wall-mounted boilers (on/off control).

  • Water valves/pumps.

  • Underfloor heating pipes (hydronic).

  • Radiator systems.

• Control Type: It is an on/off relay thermostat, typically used to switch the power to a water pump or a zone valve/actuator for the heating system.

• Low Load Rating: The maximum output is lower than the electrical heating version, rated at $\le 5A$, suitable for control signals or low-power actuators/pumps.

Smart Home & Design:

• Z-Wave Plus: Uses Z-Wave Plus (Gen 5) wireless technology for integration into a smart home hub/gateway.

• Version 2 Enhancement: The most significant upgrade in Version 2 is the ability to connect to other Z-Wave binary switch actors (like plugs or relays) via Association Groups. This allows the thermostat to directly control an on/off heating actuator without the constant need for the central Z-Wave controller to relay the command.

• Design: Features a modern look with a tempered glass panel and capacitive touch buttons.

• Installation: Requires a permanent mains power supply (AC85-260V) and is designed for flush-mount installation.

Sensing and Operation:

• Dual Sensing: Includes a built-in room temperature sensor and a humidity sensor.

• External Sensor: While its primary control is for water, it can sometimes be connected to an optional external sensor for ambient temperature or other purposes, though its main control logic is based on room temperature.

• Control Modes: Supports:

  • Manual Mode

  • Auto Mode (programmable time periods)

  • Holiday/Energy Saving Mode

• Programmable Schedule: Allows for a weekly schedule with 4 events (time periods) each day (7-day or 5+2 / 5+1+1 options).

Technical Specifications (MH7H-WH):

• Power Supply: AC85-260V, 50/60Hz.

• Max Output: $\le 5A$ (for Water Heating model).

• Self-Consumption: $\le 1W$.

• Temperature Setting Range: 5∘C to 37∘C (41∘F to 99∘F).

• Internal Temp. Sensor: NTC 15K.
