Neomitis RTE7D WIRED PROGRAMMABLE ROOM THERMOSTAT

PACK CONTAINS

INSTALLATION

Recommended locations for your thermostat.
To ensure that your thermostat provides accurate readings and controls effectively, it must be installed approximately 1.5 m above floor level on an inside wall, away from direct sunshine and any other sources of heat or cold such as radiators, cold draughts, etc.

INSTALLING BATTERIES

• Remove the batteries cover which is placed on the front of thermostat
• Insert the 2 batteries AA supplied. Note the correct polarity according to the engraving on the thermostat when inserting the batteries
• Replace the batteries cover

MOUNTING OF WALL MOUTING PLATE

• Unscrew the 2 screws under the thermostat.
• Remove the wall plate from the thermostat.
• Secure the wall plate with the two screws provided using the horizontal and vertical holes

WIRING

All wiring must be in accordance with IEE regulations. This product is for fixed wiring only.

MOUNTING OF THE THERMOSTAT

• Replace the thermostat on the wall mounting plate.
• Secure the thermostat by screwing the both locking screws under the thermostat.

OPTIMISATION EXPLAINED

Historically, most UK heating systems waste vast amounts of energy by firing unnecessarily early for most of the year. Homeowners tend to set their boiler on times based on when they wake up by guessing what time they feel that their boiler should fire in order to reach the requested target temperature; for example turning the boiler on at 6am in order to have a warm room/ home by their wake up time at 7am.

Dual function optimisation , priority to comfort or energy savings, the choice is yours:
Depending on various parameters: room inertia, ambient temperature, desired temperature, the thermostat calculates and optimizes the programming for each heating period whether set to Comfort or Savings (Eco):

In OPTI COMFORT mode, priority to comfort
In OPTI COMFORT mode, the thermostat’s inbuilt algorithm optimises in order to guarantee maximum comfort during the COMFORT programme.

In OPTI ECO mode, priority to energy savings
In OPTI ECO mode, the thermostat’s inbuilt algorithm optimises in order to guarantee maximum energy savings throughout the ECO programme.

PLEASE READ BEFORE PROGRAMMING THE THERMOSTAT
Instead of using a fixed start time, Optimum Start calculates how long the house will take to warm up depending on the temperature of the home, then fires the boiler automatically at the most efficient moment in order to reach your target temperature by your programmed time.

HOW DOES OPTIMUM START WORK?
Optimum Start works on a daily basis. You set the time that you want to be warm and Optimum Start will do the rest; for example – if you wake up at 7:30AM, then set your thermostat’s start time for 7:30AM. Optimum Start ensures that you are warm when you want to be (and not before), reducing wasted energy and saving money (up to 10% of energy costs). To change the optimisation type, refer to the installation instructions/ advanced installer settings.

Optimization feature

Overview

Dual function optimization, priority to comfort or energy savings, the choice is yours:
Depending on various parameters: room inertia, ambient temperature, and desired temperature, the thermostat calculates and optimizes the programming for each heating period whether set to Comfort or Savings (Eco):

• In OPTI ECO mode, the thermostat’s inbuilt algorithm optimizes in order to guarantee maximum energy savings throughout the ECO programme. In this mode, a slight drop in the temperature level at the beginning and end of the ECO period is allowed to maximize energy savings. The processor within the thermostat stops the boiler operation at the optimum time to slightly reduce the setpoint temperature before the end of the occupancy period. In this mode, a slight drop in the temperature level at the beginning and end of the comfort period is allowed to maximize energy savings.
• In OPTI COMFORT mode, the thermostat’s inbuilt algorithm optimizes in order to guarantee maximum comfort during the COMFORT programme. The processor within the thermostat starts the boiler operation at the optimum time to achieve the setpoint temperature at the start of the occupancy period. In this mode, the priority is given to anticipating and maintaining the comfort temperature during periods of occupancy.

Optimization choice

• Move the programming slider to the position
• Press and hold ENTER for 5 seconds to access the setting mode.
• OP appears on the display, the set mode “CONF” and its corresponding icon flash.
• Turn the dial and select th desired mode:
• OP CONF = optimization feature activated for
• OPTI COMFORT mode, priority t o c comfort
• OP ECO = Optimisation feature activated for
• OPTI E CO mod e, priority to energy efficiency
• OP OFF = Optimisation feature deactivated
• Press ENTER to save, exit setting optimisation feature and go back to the current mode.

TROUBLESHOOTING

Display disappears on thermostat.

• Check batteries.
• Replace the 2 batteries. Only use alkaline 1.5V AA (LR6) batteries.
• Do not use rechargeable batteries.

The heating does not come on or does not go off.

• Your room thermostat may have been set up close to a source of heat or on a cold wall – put it in a recommended location (see the “Installing” section on page 1 for these locations).
• Check that the communication works between the thermostat and the boiler.

You want to change the operating mode but when you move the mode slider nothing happens.

• If the lock symbol is being displayed, then the thermostat is locked.
• Unlock the thermostat by following the instructions for doing so in the “program lock” section (see page 2).

• Thermostat sensor may be influenced by a source of heat or cold.
• Check that the communication works between the thermostat and boiler.
