PERRY 1CR-CR018BS Weekly Digital Programmable Thermostat

INTRODUCTION

The daily or weekly model of the Chronothermostat can control heating systems (wall boilers, burners, local solenoid valves, floor systems) and/or conditioning systems thanks to its HEATING (WINTER) and COOLING (SUMMER) functions. It comes with a calendar with a factory-set date and time. It automatically changes standard time to summer time and vice versa. This chronothermostat’s main feature is that it can be easily programmed. It was designed with the user’s needs in mind. Settings can be changed simply by pressing a specific key instead of multiple keys. There is a key for each weekday (weekly model), as there is a key for increasing or decreasing the temperature at any time during the day. The chrono thermostat is factory-set to differentially turn ON/OFF the temperature. Hysteresis can be set from 0.1°C to 0.9°C, thus adapting to the system’s thermal inertia. It can also operate in the modulating proportional mode with cycles whose durations can be set (7-10-15-20 minutes). This maintains a stable temperature increasing the user’s comfort level. The apparatus can also advance the starting and stopping of the connected device (economy and standard intelligent operation). This allows the desired temperature to be reached at the set time. The temperature scale is Celsius and it can be adjusted by setting a correction value. Special attention is paid to energy savings. The WEEKEND function, the pause for housekeeping, and the optional block of setpoint temperatures (MAX/MIN) save energy and therefore money (these and other functions are described in the following pages).
