The external floor temperature sensor is connected to input X1, and acquires the floor temperature. If the floor temperature exceeds the parameterized temperature limit xx ºC (P14 = 1, P15 = 1, P16 = xx ºC), the heating valve is fully closed until the floor temperature returns to a level below the parameterized limit. Typical application is rooms (dry floor).
Periodic pump run function Can only be used when circulating pump or valve is controlled! This function protects the pump or valve against seizing during longer off periods. Periodic pump run is activated for 3 minutes every 24 hours at 12:00. Parameter P12 = 0 (Default) P12 = 1 Pump status Pump run off Pump run on 24 h 3 min. on 1422Z04 off 12:00 12:00 Optimum start control The purpose of optimum start control is to reach a temperature level 0.
Control behavior (P78) The new control algorithm of RDE100.. family offers a choice of control actions that can be configured via parameter P78. This means that optimum control can be selected for every type of application (factory setting “TPI slow”). 2-position, 1 K 2-Position controller with 1 [K] switching hysteresis 2-position, 0.3 K · · · TPI slow 2-Position controller with 0.3 [K] switching hysteresis. For general control situations. Provides a better comfort than 1 [K] switching hysteresis.
Minimum switching on / off time Average period time > 1 minute Approximately 10 minutes Do not use TPI fast for oil boilers or electro mechanical actuators!

Mounting and installation notes Do not mount the thermostat in niches or bookshelves, not behind curtains, not above or near heat sources, and not exposed to direct solar radiation. Mount about 1.5 m above the floor. Mounting · Mount the thermostat in a clean and dry location without direct air flow from a heating/cooling equipment, and not exposed to drip or splash water Note: When RDE100.. is equipped with either China 86 conduit box or BS4662 UK conduit box, ARG70.
Commissioning notes Commissioning After power is applied, the thermostat carries out a reset during which all LCD segments flash, indicating that the reset was made correctly. After the reset, the thermostat is ready for commissioning by qualified HVAC personnel. The control parameters of the thermostat can be set to ensure optimum performance of the entire system. Please refer to Operating Instructions CB1B1422, section "Do you want to change parameters?".
Setting parameter P14 = 1 (X1 External input = External Sensor) and parameter P15 = 0 (Temperature limitation = Off) Notes for floor heating temperature control: - External safety thermostat is needed to prevent overheating of certain floor heating systems! - Use of “Comfort setpoint lock” function (Parameter P06) is recommended.
Holiday mode When holiday mode is activated, symbol appears on the display. The set point (12 ºC) and the number of days a user is away can be readjusted by pressing touch keys + and –.
