TroubleshootingSympton Cause Action

No heat to heating zone No electrical power to thermostat Check thermostat is switched “on”, and that the fused spur is switched “on”.

Check fuse in fused spur.

Check Live and Neutral is connected to correct terminals on thermostat.

Room thermostat not set correctly Set the thermostat to a high temperature setting to “demand” heat.

Thermal actuators / UFH pump not wired correctly

Check that the thermal actuators / UFH pump are connected to the Live output terminal (3) on the thermostat.

Boiler not wired correctly Check that the boiler and pump are connected to the thermostat in accordance with the boiler manufacturers installation instructions. A volt free relay is available in the thermostat.

Boiler not set correctly Check boiler is switched “on” and controls correctly set.

Check boiler system pressure gauge to ensure system has been filled correctly. Note. Boiler will not function below the minimum system pressure.

Parameter 7 Dly Volt free relay time delay: To prevent rapid switching, the operation of the volt free relay can be delayed by up to 5 minutes after the thermostat switches “on” to demand heat. The default is 00 which means there is no time delay. The volt free relay operation will have no time delay when the thermostat switches “off” when the heating is satisfied.

Parameter 8 HitMaximum setting temperature: The maximum thermostat setting temperature can be limited to between 35° and 60°C. The default is 35°C.

Parameter 9 FacFactory re set: All factory default settings can be restored.

General Function

The Reliance touchscreen programmable thermostats combine the functions of a time clock and room thermostat into a modern, simple to use controller that allows the user to programme different temperatures for different times to suit individual requirements. It offers 7-day programming; allowing each day to be set differently, if so required. Additionally the unit can be set to 5/2-day mode allowing one set of programmes to be used for weekdays with a different set available for the weekends, and a 6/1-day mode which can be set to cater for a longer working week. Each working day allows for up-to six events to be programmed.

• 7-day, 5/2-day or 6/1-day programming options for complete flexibility• 6 programmable (time and temperature) events per working day• Pre-installed, preset time, temperature heating program• User override of temperature program setting• Manual/timed operation - user selectable• Touchscreen key lock function• Large, easy to read, back lit LCD display• Battery back up to retain settings if power failure• Frost protection if thermostat is switched off• Double temperature sensor option for underfloor heating• Available in white or black finish to suit all interior designs• Precise temperature control to +/- 1°C• Ergonomic, unobtrusive, modern styling

Parameter 3 LitMaximum floor temperature limit: The maximum floor temperature can be set for underfloor heating applications. The default is 35°C.

Parameter 4 DifSwitch differential (bandwidth): This allows the switching differential to be increased. The default is 1°C which means that the heating (or pump) will switch on 1°C below the set temperature and switch off when the set temperature is achieved. The default is 1°C.

Parameter 5 PrgProgram mode: Four program methods are selectable. 1. 5 working days + 2 non working days: This allows 6 temperature changes at defined times each week day, and 2 temperature changes at defined times at the weekend.2. 6 working days + 1 non working day: This allows 6 temperature changes at defined times each working day, and 2 temperature changes at defined times for the non working day.3. 7 day program: This allows 6 temperature changes at defined times each day of the week.4. Program off. The thermostat will be in manual mode only.The default program is 5 working days and 2 non working days.

Parameter 6 RleVolt free relay setting: The relay switching condition can be set in 2 ways:1. When the main loop output is 230Vac, the relay contacts are closed.

This is the heating demand condition (Default setting).2. When the main loop output is 0V as, the relay contacts are closed.

This is the heating satisfied condition.

Location

The Reliance touchscreen programmable room thermostats are for use in either a domestic or commercial environment and should be mounted in a suitable location free from direct sun light , a heat source, or any electrical goods as these may provide a false reading.

Mounting

Please note this programmable room thermostat is designed to fit to a standard single electrical mounting box, depth 25mm width 70mm length 70mm.

Un-clip the mounting bracket from the back of the programmable room

thermostat, secure this to the electrical mounting box using the securing screws provided, please take care to ensure the positioning lines up with the indents in the back of the casing on the programmable room thermostat.

Once wired, the programmable room thermostat, will clip on to the mounting bracket; position the top of the programmer on the bracket first and then push down the bottom to clip securely. Please do not push directly on the LCD as this may cause damage to the display.

Heating program detailsThe heating program allows you to have different temperatures through the day. For example you may want to get up in the morning with the property warm, and have it cooler while you are at work, then have it warmer in the evening, and finally have it cooler while you are sleeping.The thermostat has a pre-installed time / temperature program, with 4 programming options, these can be altered using the Advanced Settings (see page 10):• 5 working day / 2 non working day: 6 time / temperature periods for

each working day and 2 time / temperature periods for non working days (Default program).

• 6 working day / 1 non working day: 6 time / temperature periods for each working day and 2 time / temperature periods for non working days.

• 7 day program: 6 time / temperature periods for each day.• Program off: Manual operation only.See table below for details on the program setup:
