INTRODUCTION

What is a Programmable Thermostat?
A programmable room thermostat is a device that combines the functions of both a room thermostat and timed heating controller into a single unit. The programmable thermostat is used to switch the heating system in your home on and off as needed. It works by controlling the temperature according to a series of programmed temperature settings that take effect at different times of your choosing.
It’s important to note that adjusting a room thermostat to a higher setting will not make the room heat up more quickly. How quickly the room heats up depends on the design of the heating system and heat-loss of the building.
The way to set and use your programmable room / floor sensing 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 a lower temperature first, for example 18°C, and then adjust the temperature gradually up or down by one degree each day until you are comfortable with the temperature. The higher a temperature setting required will result in more energy and fuel cost.
All types of thermostats need a free flow of air to sense the best temperature, so they must not be placed in a cupboard or covered by curtains or blocked by furniture. Radiant heat created by the sun, shining directly onto the thermostat through a window and heat from nearby electric fires, wall or lamps may prevent the thermostat from reading the correct temperature in the room.

FEATURE SETTINGS EXPLAINED
The following settings are optional and in most cases do not need adjusting.
Schedule: The SnugStat thermostat provides three programming modes and can also be set to a non-programmable mode:
Weekday / Weekend (5 + 2) Programming – Allows you to edit the 4 time periods for the weekday and 4 time periods for the weekend. This is the preset setting. To change this, follow the below:

1. Press the icon to enter Feature Settings.

2. Find ‘Schedule’ and press it.
   There are four options:
   7 day programming mode – Can be programmed each day for
   4 time periods.
   24 hours mode – Every day can be edited for 4 time periods.
   Weekday/Weekend – One program can be set for Mon-Fri and another for Sat-Sun.
   None Mode – The controller will maintain the set temperature continuously.

3. Press the icon to the left of the desired icon.

4. Press the icon to save and return to the main screen.

Back Light –

• Ambient Light Dimming: If this function is enabled, the internal light sensor will detect when to dim the thermostat display as the ambient light levels drop. If you turn the room lights off, the display will dim so the SnugStat Wi-Fi Thermostat does not light up the room.

• Temperature Format: Selecting between 0C and 0F.
  Switching Differential: This function allows you to increase the switching differential of the thermostat. The system defaults to 1⁰C, meaning that when the temperature is set to 20⁰C, the thermostat will initially heat to 20⁰C then drop to 19⁰C and go back up to 20⁰C. If the value is 2⁰C, it will drop to 18⁰C, and go back to 20⁰C.

• Switching Time Delay: To prevent rapid switching, a switching delay can be entered. This function delays how often the thermostat can call for heat. This can be set from 0-15 minutes. (The default is 00, means no delay).

• Output Delay: This setting is to stop rapid switching, if set to 15min, once the thermostat stops calling for heat it will not switch on for 15 minutes.

• Away: This is the temperature maintained when the thermostat is turned ON. The range is 7-350C. The default is 70C.

• Defrost: This is the temperature maintained when the thermostat is turned OFF. The range is 5-100C. The default is 50C and is suitable for most applications.

• Sensor Selection: You can select which sensor should be used. You can select between air temperature only, remote floor temperature only, remote air sensor or air and floor sensor. When you enable both sensors you are programming the air temperature, the floor sensor is used as a floor limiting sensor and is designed to prevent the floor from overheating. The remote air sensor is only used in bathrooms and wet rooms because the thermostat is not IP rated. The remote air sensor can’t be used in tandem with the remote floor probe.

• Open Window Function: The thermostat turns the heat off for 15 minutes if it detects that the temperature drops by more than 3⁰C in less than
  1 minute. Sensor selection should be set at built in or remote air to operate correctly.

• Floor Temp Limit: The function is available when the floor sensor is enabled. You can set a floor temperature limit between 20-450C
  (default is 270C).
  Note: The Air Sensing Only Mode must not be used for controlling electric underfloor heating under wood / vinyl
  floor coverings. The controller should only be in remote floor sensor or air and floor sensor.
  Optimum Start: This function will calculate how much time the heated space needs, to ensure the required temperature you have set, at the time you have set, is achieved (assuming the heating system has been installed to meet the energy requirements of the building). For example if you require 210C at 8am, the thermostat will calculate how much time in advance, the system needs to operate to achieve this setting. This time is calculated by the thermostat in minutes per 10C room temperature rise.
