Heatmiser Slimline-RF V3 Wireless Thermostat USER MANUAL

A programmable room thermostat is both a programmer and a room thermostat. A programmer allows you to set “On” and “Off” periods to suit your own lifestyle. A room thermostat works by sensing the air temperature, switching on the heating when the air temperature falls below the thermostat setting, and switching it off once this set temperature has been reached. So a programmable room thermostat lets you choose what times you want the heating to be on, and what temperature it should reach while it is on. It will allow you to select different temperatures in your home at different times of the day (and days of the week) to meet your particular needs and preferences. Setting a programmable room thermostat to a higher temperature will not make the room heat up any faster. How quickly the room heats up depends on the design and size of the heating system. Similarly reducing the temperature setting does not affect how quickly the room cools down. Setting a programmable room thermostat to a lower temperature will result in the room being controlled at a lower temperature, and saves energy. The way to set and use your programmable room thermostat is to find the lowest temperature settings that you are comfortable with at the different times you have chosen, and then leave it alone to do its job. The best way to do this is to set the room thermostat to a low temperature – say 18°C , and then turn it up by 1°C each day until you are comfortable with the temperature. You won’t have to adjust the thermostat further. Any adjustment above this setting will waste energy and cost you more money. You are able to temporarily adjust the heating program by overriding or using the temperature hold feature. These features are explained further on pages 17 and 18 of this manual. Programmable room thermostats need a free flow of air to sense the temperature, so they must not be covered by curtains or blocked by furniture. Nearby electric fires, televisions, wall or table lamps may also prevent the thermostat from working properly.

Installation Procedure

Do
- Mount the thermostat at eye level.
- Read the instructions fully so you get the best from our product.
Don’t
- Do not install near to a direct heat source as this will affect functionality. Do not push hard on the LCD screen as this may cause irreparable damage.

The neoStat V2 is designed to be flush mounted and requires a back box of 35mm (minimum depth) to be sunk into the wall prior to installation.

Step 1 Using a small screwdriver, slightly loosen the screw from the bottom face of the thermostat. Then carefully separate the front half from the back plate.
Step 2 Place the thermostat front somewhere safe. Terminate the thermostat as shown in the diagrams on pages 28-31 of this booklet. Note: For time clock wiring connections, terminate as shown on page 38.
Step 3 Screw the thermostat back plate securely into the back box.
Step 4 Clip the front of the thermostat onto the back plate, securing it in place with the retaining screw.

Batteries

Installing the Batteries

2x AAA batteries have been supplied with this thermostat. To access the battery holder, push and release the compartment door located on the bottom face of the thermostat. The thermostat will inform you when the batteries need to be replaced by displaying the battery icon on screen. Do NOT use rechargeable batteries with this product!

Insert the batteries in the empty battery holder, ensuring that each battery is orientated for the correct polarity + / – . Push the battery holder back inside the thermostat until it is secured in its closed position

Replacing the Batteries

Batteries have a fixed lifespan and will need to be replaced occasionally to ensure the thermostat operates correctly. The thermostat will inform you when the batteries need to be replaced by displaying the battery icon on screen. Note: You must replace the batteries within 1 minute of removal in order to retain the current clock and comfort level settings.

Optional Features Explained

Feature 01 – Temperature Format: This function allows you to select between °C and °F.
Feature 02 – Switching Differential: This function allows you to increase the switching differential of the thermostat. The default is 1°C which means that with a set temperature of 20°C, the thermostat will switch the heating on at 19°C and of at 20°C. With a 2°C differential, the heating will switch on at 18°C and o at 20°C.
Feature 03 – Frost Protect: You can set whether the thermostat will maintain the frost temperature when the thermostat display is turned of. As a default, this is enabled.
Feature 04 – Output Delay: To prevent rapid switching, and output delay can be entered. This can be set from 00 – 15 minutes. The default is 00 which means there is no delay.
Feature 05 – Temperature Up/Down Limit: This function allows you to limit the use of the up and down keys. This limit is also applicable when the thermostat is locked and so allows you to give others limited control over the heating system.
Feature 06 – Air Sensor Selection: On this thermostat, you can select which sensor should be used – a built-in sensor or a remote air sensor.
Feature 07 – Optimum Start: Optimum start will delay the start-up of the heating system to the latest possible moment to avoid unnecessary heating and ensure the building is warm at the programmed time. The thermostat uses the rate of change information to calculate how long the heating needs to raise the building temperature 1°C (with a rate of change of 20, the thermostat has calculated the heating needs 20 minutes to raise the building temperature 1°C) and starts the heating accordingly.
Feature 08 – Rate of Change: For information only.
Feature 09 – Program Mode: The following program modes are available;
- 5/2 Day Programming – 4 levels for the weekdays and 4 different levels for the weekend.
- 7 Day Programming – 4 levels for each day.
- 24 Hours – 4 levels over 24 hours.
Feature 10 – Thermostat Mode: Here you can set in which mode you would like the thermostat to operate. The options are, manual (non-programmable), programmable, or programmable with hot water time clock.
