How your programmable thermostat works
When the thermostat is in the AUTO mode, it will operate according to the
times and temperatures that have been programmed. The user can select from 6
different programs per day – each with a time and a temperature.
There is no OFF time, only a higher and a lower temperature.
If the user wants the thermostat to be OFF at a certain time, set the
temperature for this time to be low. The thermostat will turn ON if the room
temperature is lower than the setpoint for the current period.
Example: If P1 is set to be 21°C at 6am, and if P2 is set to be 10°C at 8am,
the thermostat will look for the temperature to be 21°C between 6am and 8am.

When the thermostat is in Normal mode, the thermostat will try to reach the
target temperature at the program time.
Example: Program 1 on the thermostat is 21°C for 06:30am and the room temperature is 18°C. The thermostat will start the heating at 06:30am and
the room temperature will start to increase.
32
RFRPV2 Room Thermostat CP4V2
OS (Optimum Start Mode) When the thermostat is in Optimum Start mode, the
thermostat will try to reach the target temperature by the start time of the
next program. This is done by setting the Ti (time interval) on the thermostat
in this menu to 10, 15, 20, 25 or 30. This will allow the thermostat 10, 15,
20, 25 or 30 minutes to increase the room temperature by 1°C. Ti can be set
when OS is selected in the installer menu. 20°C To achieve the target
temperature when the program starts, the thermostat will read:
1. The Room Temperature (RT) 2. The Setpoint Temperature (ST) 3. The Target
Temperature Difference (TTD) is the difference
between the setpoint temperature and the room temperature . The time (in
minutes) that it will take to overcome (TTD) is called Optimum Start Time
(OST) and its maximum value is 3 hours = 180 mins. This is subtracted from the
start time. As the temperature increases the thermostat will recalculate the
OST if the temperature is increasing too quickly.

P0 1 Operating Mode Continued
TPI (Time Proportional & Integral Mode)
When the thermostat is in TPI mode and the temperature is rising in the zone
and falls into the Proportional Bandwidth section, TPI will start to affect
the thermostats operation. The thermostat will turn on and off as it gains
heat so that it doesn’t overshoot the setpoint by too much. It will also turn
on if the temperature is falling so it doesn’t undershoot the setpoint which
will leave the user with a more comfortable level of heat.
There are 2 settings that will affect the thermostats operation:
1. CYC – No. of Heating Cycles per Hour: 6 Cycles
This value will decide how often the thermostat will cycle the heating on and
off when trying to achieve the setpoint temperature. You can select 2/3/6 or
12.
2. Pb – Proportional Bandwidth: 2°C
This value refers to the temperature below the setpoint at which the
thermostat will start to operate in TPI Control. You can set this temperature
from 1.5°C to 3.0°C in 0.1°C increments.

Controlling an OpenTherm® Boiler with multiple CP4V2
It is possible to have up to six CP4V2 thermostats controlling one OpenTherm®
boiler. To do this it is necessary to make one of the RF1B receivers into a
Hub Receiver. This Hub Receiver will receive data from all of the RFRPV2
thermostats and relay this information to the boiler via OpenTherm®.
Note: The Hub Receiver should have a wired OpenTherm® connection to the
boiler. When installing multiple receivers – see important on page 15. Making
your RF1B receiver into a Hub Receiver:
1. The RF1B has an LED to indicate if it is a Hub.
2. Press and hold Manual & Connect for 5 seconds to make the receiver a Hub
or Branch.
Note: A Hub receiver is the master receiver in multiple zone installations. A
branch receiver is used for connecting additional zones. See Page 50 for
System Architecture.
Note: A Hub receiver can connect to a GW04 Wi-FI Gateway.
54
RFRPV2 OpenTherm® Instructions
Identifying if a receiver is a Hub Receiver: 1. If the Hub LED is illuminated
the RF1B is a Hub receiver. Pairing the RF1B receivers together: 1. Hold
Connect on the Hub receiver for 3 seconds.
The RF LED will begin to flash. 2. Hold Connect on the next receiver to be
paired. The RF LED
will flash 3 times and then stop. This receiver is now linked. 3. Repeat this
process to pair more, up to a maximum of 6 receivers. 4. Press Manual on the
hub to return to normal operation. Once all units have been paired, allow time
for the receivers to begin to communicate and receive OpenTherm® information
from the boiler. This may take approximately 2 5 minutes. Disconnecting the
RF1B receiver from other Receivers: 1. Hold Manual & Connect on the Hub
receiver until the Hub LED turns off. This will clear the connection to the
branch receivers.
