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.

1
Check boiler system pressure gauge
to ensure system has been filled
correctly.
Note. Boiler will not function below
the minimum system pressure.
Error message in display:
ER1
Internal temperature sensor failure
Check that Parameter 2 Sen in
Advanced settings is correctly set.
Error message in display:
ER2
External sensor failure or incorrect
parameter setting.
Check that external sensor is
connected correctly.
Check that Parameter 2 Sen in
Advanced settings is correctly set.
Thermostat always in Manual mode
i.e. Timed program control mode
cannot be set.
Incorrect parameter setting
Check Parameter 5 Prg in Advanced
settings is correctly set.
Note. OF is Manual mode.
Cannot set time / temperature
program for each day
Check Parameter 5 Prg in Advanced
settings is correctly set.
Poor room temperature control.
Check Parameter 4 Dif in Advanced
settings is correctly set.
14
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 Hit
Maximum setting temperature: The maximum thermostat setting
temperature can be limited to between 35° and 60°C. The default is 35°C.
Parameter 9 Fac
Factory 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.

Ergonomic, unobtrusive, modern styling
Parameter 3 Lit
Maximum floor temperature limit: The maximum floor temperature can
be set for underfloor heating applications. The default is 35°C.
Parameter 4 Dif
Switch 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 Prg
Program 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 Rle
Volt 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.

Heating program details
The 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.
