Arrangement of a vehicle auxiliary heater with a regulating device and control unit inside a vehicle
First Claim
1. An arrangement for auxiliary heating of a vehicle, the arrangement comprising:
- a heating unit located in an area of a floor of a cab of the vehicle, said heating unit including a control device;
an operating part positioned in an interior space of the vehicle at a distance spaced from said heater unit;
connection means for functionally connecting said operating part to said heating unit, said connection means being a bidirectional radio connections;
said operating part has a first HF module with a first transmitter and receiver part;
said control device has a second HF module with a second transmitter and receiver part;
said operating part has a microprocessor with means for timer functions, said operating part also including a coding and decoding circuit, said timer functions being in wired connection with said first HF module of said operating part via said coding and decoding circuit, said microprocessor includes means for diagnostic functions.

Abstract
In an arrangement of a vehicle auxiliary heater with an integrated regulating device in the region of the floor in the vehicle cab and a control unit remote from the auxiliary heater, e.g. in the region of the dashboard or on an inner wall of the vehicle, it is proposed that the control unit be operationally connected to the regulation device wirelessly via a bidirectional radio link in which use is made of an r.f. unit with a first r.f. module on the operating side with a transmission and reception section and a second r.f. module on the control device side with a second transmission and a reception section. This obviates the need for the complicated laying of prior art wired connections between the control unit and the regulating device of the auxiliary vehicle heater, making the heater particularly suitable for subsequent fitting in commercial vehicles.

9. A method for auxiliary heating of a vehicle, the method comprising the steps;
-
providing a heating unit located in an area of a floor of a cab of the vehicle, said heating unit including a control device; an operating part positioned in an interior space of the vehicle at a distance spaced from said heater unit; entering desired heating parameters into said operating part; converting said desired heating parameters into control signals for said heating unit with a coding circuit; transmitting said control signals by radio from said operating part to said heating unit; said control device of said heating unit implementing said control signals; said control device determining actual operating values of said heating unit; transmitting said actual operating values from said control device to said operating part by radio; converting said actual operating values at said operating part into actual heating parameters; displaying said actual heating parameters from said operating part; performing diagnostic functions by radio from said operating part to said heating unit, and returning diagnostic data from said heating unit to said operating part; displaying said diagnostic data from said operating part.
