Introduction
The CH115RF is a three-temperature thermostat suitable to control the room temperature both in heating
and in air-conditioning operating conditions. These
controls are sent to the CH173D actuator, supplied
separately, that communicates in radio-frequency
with the CH115RF.
The CH115RF is powered by two AA 1.5V batteries
and is suitable to remotely control a relay. The thermostat measures the room temperature through an
internal probe and keeps the “set point” by controlling
the relay switching on and off.
The wide display shows the measured room temperature, the current program and the selected season.
Three operating modes (Comfort, Economy and
OFF/Antifreeze) are available and the user can select
to operate the thermostat with the heating function
(Winter) or the air-conditioning function (Summer).
Settings and data are stored in a non-volatile memory
suitable to retain them even when batteries are not
tted.
The thermostat comes in three colors: white, Silver
(CH116RF) and anthracite Black (CH117RF).

User’s manual
First of all, make sure that the self-learning procedure
has been performed yet (page 8); moreover, verify
8
that both the CH115RF and the CH173D are 30 meters far from each other at the most In fact, this distance represents the free air maximum range for the
radio frequency modules used by the thermostat and
the actuator. Please note that the range will decrease
if obstacles are found between the CH115RF and the
CH173D.
To start the thermostat after having installed it, proceed as follows:
1. Select Summer / Winter operation.
2. Select the operating mode.

Summer / Winter Selection
To switch from Winter operation (i.e.: heating system)
to Summer operation (i.e.: air-conditioning system),
